Actually, "blah, blah, blah" is more cogent and intellectually honest that the screeds posted by that one. After refutation, his posts recite the same defeated arguments and contain little more than ad hominem's looking for a place to settle. But, those of us who have accepted the Truth of God's plan, are instructed to speak against all that hogwash.
Roman Catholicism exists because too may people are too willing to accept those things taught them at an early age, without questioning the veracity thereof. Scripture offers everything necessary for Salvation. Jesus paid the price for our sinful nature and our sinful lives. There is nothing to add to that, and looking at their practices, it is clear they seek tangible aspects of religion, over the comfort (and sometimes Discomfort) of His indwelling Holy Spirit.
Paul sums it up nicely in his letter to the Romans. It is difficult to excerpt only one part of that letter, but one that stands out in my mind is his reflection on human nature... his own...
Romans 7: 14 We know that the law is spiritual; but I am unspiritual, sold as a slave to sin. 15 I do not understand what I do. For what I want to do I do not do, but what I hate I do. 16 And if I do what I do not want to do, I agree that the law is good. 17 As it is, it is no longer I myself who do it, but it is sin living in me. 18 For I know that good itself does not dwell in me, that is, in my sinful nature. For I have the desire to do what is good, but I cannot carry it out. 19 For I do not do the good I want to do, but the evil I do not want to do—this I keep on doing. 20 Now if I do what I do not want to do, it is no longer I who do it, but it is sin living in me that does it.
21 So I find this law at work: Although I want to do good, evil is right there with me. 22 For in my inner being I delight in God’s law; 23 but I see another law at work in me, waging war against the law of my mind and making me a prisoner of the law of sin at work within me. 24 What a wretched man I am! Who will rescue me from this body that is subject to death? 25 Thanks be to God, who delivers me through Jesus Christ our Lord!
So then, I myself in my mind am a slave to God’s law, but in my sinful nature a slave to the law of sin.
