Statements 1-4 are either irrelevant or at best tangential to the issue. After all, even if you have no dispute with any of those 4 assertions, none of those actually establish that praying to Mary, and according her the level of worship that Catholics do, is appropriate.
Number 5 touches on the salient point, that of intercession, but ignores some key matters. First, though the Bible provides evidence of Christians being told to ask each other to pray for them, there is not a single instance of anyone being told to user prayer in order to make that request. Every example is only of one person simply asking another living person to pray for them.
Now, the Catholic counterpoint to that is to say that Christians, living or dead, are all part of the “communion of saints”, so it is therefore no different to ask a dead Christian, such as Mary to pray for you, than it is to ask a living Christian. However, I see a couple holes in that argument.
First, in order for us to accept this argument, the person being prayed to must be part of this communion, or the point is of no consequence. This is only important in the case of asking those not living on earth for intercession, since there is a specific Biblical prohibition against communicating with the dead or with spirits that is relevant to this case. Catholics can argue that Christians who have part in Christ’s resurrection are not “dead” once their bodies die on earth, thus exempting prayer to them from this prohibition. However, only if one was certain of the person’s spiritual condition, be it in heaven, hell, or somewhere else, could one be certain that praying to them would be acceptable and not an act of divination or spiritualism. Thus, one must accept the Catholic Church’s proclamations of the status of Saints such as Mary as absolute, in order to think that this type of prayer is not fraught with danger.
Secondly, we know that living Christians can hear our request and respond, since they are alive and this is just factual observation. On the other hand, we have no real evidence or scriptural examples to say Mary or others who may be in Heaven can actually hear our prayers, or have something approaching omniscience to be able to hear the prayers of multitudes around the world, even those praying silently. Again, we must take the Catholic Church’s opinion on the matter as the absolute truth, or we can’t easily overlook this issue.
Finally, these Catholic doctrines on Mary deal with much more than the simple matter of one Christian saying a prayer for another. The practice of praying to Mary and other Saints imply that their intercessions are more efficacious than the intercessions of others. This idea has a lot of repercussions, and there are more than a few arguments that can be raised against it.
Also, the doctrines on Mary and the saints involve not only simple prayers of intercession, but prayers of reverence. Again, the Catholics invoke the “communion of saints”, as well as the Commandment to honor your father and mother, to answer this objection. Still, the reverence shown to some saints, and especially to Mary, goes well beyond the practice of showing respect to people on earth, and it can be argued that it approaches the level or giving worship to them that is due only to God. The Catholic Church assures us that this level of worship is not inappropriate, but again, we have to accept that they are absolutely correct on that matter, or there is a problem not easily ignored.
In the end, it simply boils down to trusting the authority of the Catholic Church’s doctrine on the matter, in order to put these objections aside. If you are a Catholic, then you will accept that authority, and see no issues at all with these practices. For non-Catholics, there are plenty of reasons to question and object to the practices, but the responses all boil down to “we don’t have to worry about that because the Church says it’s okay”.
Another of the seemingly daily thread promoting the Roman church, perhaps they gain indulgences. In any case, the tendency of carnal religion flesh is to think of mortals above that which is written, whether it Benny Hinn or Mary.
In the the Catholic tendency to almost deify Mary, it is taught by Catholics*,
as Christ was sinless, so Mary was;
as the Lord remained a virgin, so Mary;
as Christ was called the Son of God, indicating ontological oneness, so Mary is called the Mother of God (which easily infers the same, and is not the language of Scripture);
as the emphasis is upon Christ as the Creator through whom God (the Father) made all things, including Mary, so it is emphasized that uniquely to her, Jesus owes His Precious Blood, shed for the salvation of mankind, (the logic behind which can lead back to Eve);
as Catholics (adding error to error) believe Christ gave His actual flesh and blood to be eaten, so it is emphasized that Mary gave Him this, being fashioned out of Mary's pure blood and even being kneaded with the admixture of her virginal milk, so that she can say, "Come and eat my bread, drink the wine I have prepared" (Prov. 9:5);
as Scripture declares that Christ suffered for our sins, so Mary is said to have done so also;
as Christ saves us from the condemnation and death resulting from the fault of Adam, so it is taught that man was condemned through the fault of Eve, the root of death, but that we are saved through the merits of Mary; who was the source of life for everyone.
as the Lord was bodily ascended into Heaven, so Mary also was;
as Christ is given all power in heaven and in earth, so Mary is surpassing in power all the angels and saints in Heaven.
as Christ is the King of the saints and over all kings, (Rv. 15:3; 17:14; 19:16) so Mary is made Queen of Heaven and the greatest saint, and that Next to God, she deserves the highest praise;
as the Father made Christ Lord over all things, so Mary is enthroned (all other believers have to wait for their crowns) and exalted by the Lord as Queen over all things;
as Christ is highly exalted above all under the Father, so Mary is declared to be the greatest saint of all, and as having a certain equality with the Heavenly Father;
as Christ ever liveth to make intercession for the saints, so is Mary said to do so;
as all things come from the Father through the Son, so Mary is made to be the dispenser of all grace;
as Christ is given all power on Heaven and on earth, Mary is said to have (showing some restraint) almost unlimited power;
as no man comes to the Father but through the Son, so it is taught that no one can come to the Son except through Mary in Heaven;
and as the Lord called souls to come to Him to be given life and salvation, so (in misappropriation of the words of Scripture) it is said of Mary, He that shall find me shall find life, and shall have salvation from the Lord; that through her are obtained every hope, every grace, and all salvation. For this is His will, that we obtain everything through Mary.
And as Christ is given many titles of honor, so Mary also is, except that she is honored with more titles than the Lord Himself.
Finally, although (technically) Mary is not to be worshiped in the same sense that God is worshiped, yet the distinctions between devotion to Mary and the worship of God are quite fine, and much due to the psychological appeal of a heavenly mother (especially among those for whom Scripture is not supreme), then the historical practice of Catholics has been to exalt Mary above that which is written, (1Cor. 4:6) and thus, "By the sixteenth century, as evidenced by the spiritual struggles of the Reformers, the image of Mary had largely eclipsed the centrality of Jesus Christ in the life of believers." (Robert C. Broderick, ed., The Catholic Encyclopedia, revised and updated; NY: Thomas Nelson Publishers, 1987, pp.32,33)
The practice of praying to departed saints and Mary was one that developed, helped by pagan influences, as while Scripture provides no example of any believer praying to anyone in Heaven by the Lord, this was a practice of pagans, including to the Queen of Heaven. (Jer. 44:17,18,19,25). The Catholic Encyclopedia admits that a further reinforcement of this idea, was derived from the cult of the angels, which, while pre-Christian in its origin, was heartily embraced by the faithful of the sub-Apostolic age. It seems to have been only as a sequel of some such development that men turned to implore the intercession of the Blessed Virgin. This at least is the common opinion among scholars, though it would perhaps be dangerous to speak too positively. Evidence regarding the popular practice of the early centuries is almost entirely lacking..., (Catholic Encyclopedia > Devotion to the Blessed Virgin Mary) but which it imagines came from the apostles who never exampled or instructed it, but who instead showed that the believer has immediate access to God in the Divine Christ, (Heb. 10:19), who is the all sufficient and immediate intercessor between God (the Father) and man. (Heb. 2:17,18; 4:15,16) To the glory of God
I would also like to say that while Roman Catholics condescend to using Scripture in attempting to substantiate to evangelicals that what they hold to is Scriptural, yet in reality neither the Mariology of Catholicism or assurance of doctrine is based upon the weight of Scriptural warrant, but it rests upon the premise of the self-proclaimed authority of Rome, with her assuredly infallible magisterium (which infallibly defined herself as being infallible, when speaking in accordance with her infallibly defined scope and subject-based formula), which is held to be able to provide such assurance.
Therefore any appeal to Scripture by Roman Catholic apologists as if it could provide assurance of truth is ultimately in order to convince souls that this is not the way to obtain certitude, and instead their goal must be to convince souls to make a fallible decision to place implicit trust in the assuredly infallible magisterium (AIM) of Rome, as if it were God (though Roman Catholics must discern which pronouncements, of out many candidates, are infallible).
Recognized Roman Catholic authorities and other web apologists will sometimes admit that, as the Catholic Encyclopedia states, "no direct or categorical and stringent proof of the dogma can be brought forward from Scripture" for the Immaculate Conception, and which understatement also applies to PV.
While Catholic authorities such as Cardinal Newman have attempted to explain the lack of Scriptural support by asserting that Christians have never gone to Scripture for proof of their doctrines, till there was actual need, from the pressure of controversy, (Anglican Difficulties, London, 1885, II, 54), the reliance upon Scripture to establish truth claims in Scripture does not allow the lack of support for these Marian excesses.
Ratzinger acknowledged that Mary, in the gospel tradition is quite marginal. (God and the world; p. 296) unlike to souls like Peter and Paul, the latter of whom sees relative little emphasis by Catholics, especially as compared with Mary. And because Scripture does not say what the Catholic wants it to say about Mary, and due to the second class (at best) status of Scripture for Catholics, what the Catholic must attempt to do is to defend a tradition by wresting texts of Scripture to support it, often going to extrapolative extremes, and which actually demeans Scripture, rather than honoring it like as he does the Catholic Mary.
Scripture no where states or teaches an exception for Mary as regards not being a sinner, or for her being a perpetually sinless virgin and having a sexless marriage (contrary to its description: Gn. 2:24; Mt. 19:4,5), who is ascended to Heaven, and who is already crowned (which happens after the resurrection) and enthroned as Queen of Heaven with almost unlimited power, including having the ability to process virtually unlimited prayer requests, (the Holy Spirit provides zero examples of prayer to anyone in Heaven but the Lord, or in its instructions on who to pray to), and who is even set forth by some notable Catholics as a more immediate and superior recourse for help than Christ Himself,
Such an absence of real substantiation is contrary to the manifest practice of the Holy Spirit in stating similar and even lesser exceptions to the norm by notable subjects, from the blood of righteous Abel, (Gn. 4:10; Mt. 23:35) to the age of Methuselah, (Gn. 5:27) to the strength of Samson, (Jdg. 4:4,16; 16:12,29,30) to the number of toes of the Philistine giant, (2Sam. 21:20), to the special diet of the Baptist, (Mt. 3:4) to Joseph being a just man, (Mt. 1:19) to the supernatural transport of Phillip, (Acts 8:40) to Jesus being sinless, which He is said at least twice to be. (2Cor. 5:21; 1Pt. 2:22)
In addition, as such claims for the Catholic Mary are (sometimes extreme) exceptions to the norm, then the burden of proof is upon the Catholic to established them, and not upon us, any more then we must disprove the existence of the Mormonic angel Moroni.
As evangelical apologist Steve Hays argues, "If the evidence is uncertain, then our position should be uncertain; not: our evidence is uncertain; therefore, it's certain that Mary was a lifelong virgin. If the evidence is uncertain, then that hardly warrants a certain conclusion.
Yet some of the Mariology referred to is approved teaching, some of it even being dogma, while the lack of censure of other claims can amount to implicit approval.
In a rare instance of a mild form of reproof of excessive Marian exaltation, no less a devotee of Mary than Cardinal Ratzinger at least recognized that the title Co-redemptrix departs to too great an extent from the language of Scripture and of the Fathers and therefore gives rise to misunderstandings (see comments on Co-redemptrix below), Yet as regards Scripture, this is also true of other aspects of Catholic exaltation of Mary, which depart too greatly from the sober and balanced descriptions given of Mary in Scripture, showing how she was a holy saint and a virgin, but not going beyond into the extremes of Catholic devotion, in which the Roman Catholic apologists add to their transgressions in their attempts to find support from Scripture by many unwarranted extrapolations.
*Catholic ascriptions to Mary (supplementary to this link):
The recourse we have to Mary in prayer follows upon the office she continuously fills by the side of the throne of God as Mediatrix of Divine grace; being by worthiness and by merit most acceptable to Him, and, therefore, surpassing in power all the angels and saints in Heaven. Iucunda Semper Expectatione, Pope Leo XIII, 1894
Moreover, one must remember that the Blood of Christ shed for our sake and those members in which He offers to His Father the wounds He received, the price of our liberty, are no other than the flesh and blood of the virgin, since the flesh of Jesus is the flesh of Mary, and however much it was exalted in the glory of His resurrection, nevertheless the nature of His flesh derived from Mary remained and still remains the same FIdentem Piumque Animum; de Assumpt.

..to her, Jesus owes His Precious Blood...Next to God, she deserves the highest praise....no creature, can ever be compared to her: "To what shall I compare thee, or to whom shall I liken thee, O daughter of Jerusalem."

..all graces of the Precious Blood come through Mary. No grace is given without her intercession. http://www.salvemariaregina.info/SalveMariaRegina/SMR-098.html
We know, too, that united to the Divinity in the Eucharist there is Jesus' Body and Blood taken from the body and blood of the Blessed Virgin. Therefore at every Holy Communion we receive, it would be quite correct, and a very beautiful thing, to take notice of our Holy Mother's sweet and mysterious presence, inseparably united with Jesus in the Host....the blood of Jesus is the maternal blood of Mary...
Go with this ineffable chaste thought to the banquet of God and you will find in the Blood of the Son the nourishment of the Mother.
..in Jesus is always the Immaculate flesh and the Virginal blood of His Most Holy Mother which penetrates into our hearts and inebriates our souls.
What is needed is a mother who may eat this supersubstantial Bread, transform it into her milk, and in this way feed her poor children. This mother is Mary. She nourishes herself with the Word and transforms It into the Sacred Humanity. She transforms It into Flesh and Blood, i.e., into this sweetest of milk which is called the Eucharist."..
"O Christian who comest full of faith to receive the Bread of life, eat It worthily, and remember that It was fashioned out of Mary's pure blood." Mary can quite rightfully beckon to us and speak to us in the words of the inspired prophet, "Come and eat my bread, drink the wine I have prepared" (Prov. 9:5)...
Thus every time we go to Holy Communion, something sweet to recall is that Jesus in the Blessed Sacrament is the Bread of Life produced from Mary with the flour of her Immaculate flesh, kneaded with the admixture of her virginal milk. http://www.catholictradition.org/Mary/virgin-eucharist.htm
"The union between the Immaculata and the Holy Spirit is so inexpressible, yet so perfect, that the Holy Spirit acts only by the Most Blessed Virgin, his Spouse. This is why she is the mediatrix of all graces given by the Holy Spirit. And since every grace is a gift of God the Father through the Son and by the Holy Spirit, it follows that there is no grace which Mary cannot dispose of as her own, which is not given to her for this purpose."
