But according to the Bible Jesus himself did not require baptism or the Lord's table as either a necessary or sufficient condition for salvation:
Luke 23:39-43 English Standard Version (ESV)One of the criminals who were hanged railed at him, saying, “Are you not the Christ? Save yourself and us!” But the other rebuked him, saying, “Do you not fear God, since you are under the same sentence of condemnation? And we indeed justly, for we are receiving the due reward of our deeds; but this man has done nothing wrong.” And he said, “Jesus, remember me when you come into your kingdom.” And he said to him, “Truly, I say to you, today you will be with me in Paradise.”
Throughout the NT, their are many examples of Jesus lauding those of faith (the centurion, the diseased woman touching the hem of his garment, the thankful leper, etc.).
Paul waxes constantly about the role in salvation played by faith. But our ultimate fate is up to sovereign God alone. We of our own are powerless to do anything to save ourselves. It is only through God calling us that we can come to him:
Romans 8:28-30 English Standard Version (ESV)Rather than hurl Bible bombs at one another, let us all be truly, humbly thankful that sovereign God sent his only begotten Son as propitiation for our sins, and that he chose us all, we who love Him, for His own.And we know that for those who love God all things work together for good, for those who are called according to his purpose. For those whom he foreknew he also predestined to be conformed to the image of his Son, in order that he might be the firstborn among many brothers. And those whom he predestined he also called, and those whom he called he also justified, and those whom he justified he also glorified.
Oh really? Why don't you believe the words of Jesus himself?
John 3
5 Jesus answered, "Truly, truly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God.
