About the salvation of the thief not being by faith alone - what about the Centurion? The Centurion absolutely was not a Christian or a Catholic yet his faith (as Jesus Himself called it) was instrumental in the commission of a Miracle.
Not so. Salvation is through Jesus Christ, not a church.
One becomes part of the body of Christ when they are saved, but that is not by default becoming part of any denomination.
The Sacraments of the Church *are* ordinarily the means by which God dispenses His sanctifying Grace... though, again, it's possible in "emergency situations" for that grace to be given to those who do not have access to them.
That's not Scriptural in the least. There is not one verse in Scripture that supports that.
On the contrary, the grace of God is LAVISHED on us through faith.
Ephesians 1:3-10 Blessed be the God and Father of our Lord Jesus Christ, who has blessed us in Christ with every spiritual blessing in the heavenly places, even as he chose us in him before the foundation of the world, that we should be holy and blameless before him. In love he predestined us for adoption as sons through Jesus Christ, according to the purpose of his will, to the praise of his glorious grace, with which he has blessed us in the Beloved. In him we have redemption through his blood, the forgiveness of our trespasses, according to the riches of his grace, which he lavished upon us, in all wisdom and insight making known to us the mystery of his will, according to his purpose, which he set forth in Christ as a plan for the fullness of time, to unite all things in him, things in heaven and things on earth.
Romans 5:1-2 Therefore, since we have been justified by faith, we have peace with God through our Lord Jesus Christ. Through him we have also obtained access by faith into this grace in which we stand, and we rejoice in hope of the glory of God.
John 1:14-17 And the Word became flesh and dwelt among us, and we have seen his glory, glory as of the only Son from the Father, full of grace and truth. (John bore witness about him, and cried out, “This was he of whom I said, ‘He who comes after me ranks before me, because he was before me.’”) For from his fullness we have all received, grace upon grace. For the law was given through Moses; grace and truth came through Jesus Christ.
Not exactly. He didn't have a long life (or freedom) in which to be faithful, obedient, etc., so his is a special case (as would be the case of an infant who dies... the Church supplies the needed faith, even though the child has no capacity to choose faith, as yet).
The church supplies nothing for attaining spiritual life.
Salvation is a gift freely given and guaranteed.
When a person believes and is saved, they are sealed with the Holy Spirit until the day of redemption.
John 5:24 Truly, truly, I say to you, whoever hears my word and believes him who sent me has eternal life. He does not come into judgment, but has passed from death to life.
John 10:25-30 Jesus answered them, “I told you, and you do not believe. The works that I do in my Father's name bear witness about me, but you do not believe because you are not among my sheep. My sheep hear my voice, and I know them, and they follow me. I give them eternal life, and they will never perish, and no one will snatch them out of my hand. My Father, who has given them to me, is greater than all, and no one is able to snatch them out of the Father's hand. I and the Father are one.”
1 Corinthians 1:4-8 I give thanks to my God always for you because of the grace of God that was given you in Christ Jesus,that in every way you were enriched in him in all speech and all knowledge—even as the testimony about Christ was confirmed among you—so that you are not lacking in any gift, as you wait for the revealing of our Lord Jesus Christ, who will sustain you to the end, guiltless in the day of our Lord Jesus Christ.
2 Corinthians 1:21-22 And it is God who establishes us with you in Christ, and has anointed us, and who has also put his seal on us and given us his Spirit in our hearts as a guarantee.
2 Corinthians 5:4-8 For while we are still in this tent, we groan, being burdened—not that we would be unclothed, but that we would be further clothed, so that what is mortal may be swallowed up by life. He who has prepared us for this very thing is God, who has given us the Spirit as a guarantee.
So we are always of good courage. We know that while we are at home in the body we are away from the Lord, for we walk by faith, not by sight. Yes, we are of good courage, and we would rather be away from the body and at home with the Lord.
Ephesians 1:13-14 In him you also, when you heard the word of truth, the gospel of your salvation, and believed in him, were sealed with the promised Holy Spirit, who is the guarantee of our inheritance until we acquire possession of it, to the praise of his glory.
Ephesians 4:30 And do not grieve the Holy Spirit of God, by whom you were sealed for the day of redemption.
Colossians 1:13-14 He has delivered us from the domain of darkness and transferred us to the kingdom of his beloved Son, in whom we have redemption, the forgiveness of sins.
Colossians 2:13-14 And you, who were dead in your trespasses and the uncircumcision of your flesh, God made alive together with him, having forgiven us all our trespasses, by canceling the record of debt that stood against us with its legal demands. This he set aside, nailing it to the cross.
Colossians 3:3 For you have died, and your life is hidden with Christ in God.
1 Peter 1:3-5 Blessed be the God and Father of our Lord Jesus Christ! According to his great mercy, he has caused us to be born again to a living hope through the resurrection of Jesus Christ from the dead, to an inheritance that is imperishable, undefiled, and unfading, kept in heaven for you, who by God's power are being guarded through faith for a salvation ready to be revealed in the last time.

2 Corinthians 1:21-22 Now he which stablisheth us with you in Christ, and hath anointed us, is God; Who hath also sealed us, and given the earnest of the Spirit in our hearts.
For which the Greek, from the Byzantine, is:
2Corinthians 1:21-22 ο δε βεβαιων ημας συν υμιν εις χριστον και χρισας ημας θεος ο και σφραγισαμενος ημας και δους τον αρραβωνα του πνευματος εν ταις καρδιαις ημων
The first word in bold above is “bebaion,” the idea of confirmation, frequently used in commercial settings to confirm a bargain. Which of course makes sense of the remaining terms used here, which are also elements of a secured contract.
The second word in bold above is “sphragisamenos,” being sealed is to be marked by the signature, signet ring, or other unique proof of identity, that we belong to God, and this sealing is done by God, who is the one taking action in this verse. We do not and cannot seal ourselves. We do not, by our own powers, have access to God’s “signet ring.”
The third bolded word above is “arrabona,” and indicates what we might loosely refer to as earnest money, but in Hebrew culture conveys more the idea of a pledge of covenant, a security given as a guarantee that the deal will go through, though we only receive part payment at the beginning. See ערב for the related Hebrew stem indicating “pledge.”
