Sure...It's right here...
Joh_20:31 But these are written, that ye might believe that Jesus is the Christ, the Son of God; and that believing ye might have life through his name.
And here...
1Jn_5:13 These things have I written unto you that believe on the name of the Son of God; that ye may know that ye have eternal life, and that ye may believe on the name of the Son of God.
It's just spelled a little bit differently than you're used to...Everything we need to learn about how to attain salvation is written in the scriptures...That is clear...I'd say that puts scripture ALONE and BY ITSELF...
1Jn 1:4 And these things write we unto you, that your joy may be full.
1Jn 2:1 My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous:
1Jn 2:2 And he is the propitiation for our sins: and not for ours only, but also for the sins of the whole world.
1Jn 2:13 I write unto you, fathers, because ye have known him that is from the beginning. I write unto you, young men, because ye have overcome the wicked one. I write unto you, little children, because ye have known the Father.
1Jn 2:14 I have written unto you, fathers, because ye have known him that is from the beginning. I have written unto you, young men, because ye are strong, and the word of God abideth in you, and ye have overcome the wicked one.
1Jn 2:26 These things have I written unto you concerning them that seduce you.
1Jn 2:27 But the anointing which ye have received of him abideth in you, and ye need not that any man teach you: but as the same anointing teacheth you of all things, and is truth, and is no lie, and even as it hath taught you, ye shall abide in him.
2Pe_3:15 And account that the longsuffering of our Lord is salvation; even as our beloved brother Paul also according to the wisdom given unto him hath written unto you;
We have it all, in the scriptures...Scripture Alone...And we have it all before the first Catholic Church Father or Doctor ever showed up...
And what's more, we no only have everything we need to get saved, build our churches and worship God, we have numerous warnings and instructions how to identify those false religions who would usurp the authority of the scriptures...And the apostle Paul lays one on us here:
2Co 12:6 For though I would desire to glory, I shall not be a fool; for I will say the truth: but now I forbear, lest any man should think of me above that which he seeth me to be, or that he heareth of me.
Paul, the greatest of the Apostles tells us to look upon him as a mere man...No Vickar, no Cardinal or Arch Bishop...Just a sinner saved by grace, chosen by God to preaching the word of God...No fancy clothes, no throne and certainly not allowing anyone to bow down to him...
Wow - too bad for all those early Christians, especially those who were martyred before the “Scripture Alone” was written and compiled, those who were unable to read or who could not afford a scarce handwritten document. Guess it was just bad timing for them, huh?
