Let me rephrase that.
All men are born to seek God. Some choose to do otherwise due to their free will.
All men are born to seek God. Some choose to do otherwise due to their free will."
No, they are not. And, the Scriptures know nothing of a man's "free will". This is another error promulgated by Rome. The very well-documented Good News of the Scripture is that man is enslaved to his darkened, broken nature. He does not seek God; he is at war with God (whether it appears to him as such, or not).
God, before the foundation of the world, elected some for whom He would provide a sacrifice and rescue in Jesus. At a moment of His choosing, He draws them, adopts them, breaks their hearts and grants them faith. They begin to wake up to the fact that they were blind, but now they see. This is the unmerited favor of grace so clearly taught in the Bible. If you would like all of the citations that support this message, let me know.
The requirement of joining the RCC is a doctrine from the pit of hell. God has already joined every chosen believer to the true spiritual "assembly of the first-born", what many have come to call a "church". But, there is no "Church" as in a Roman organization. There is no pope, no sacerdotalism, no purgatory, there are no indulgences, no sacraments, no absolutions done by men. There is no transubstantiation, no mary adoration, no canonization of men/women. These are all trappings of Rome.
We entreat you, if God permits it, to let go of the baggage added by Rome and embrace Jesus, alone. In Him is the, "once and for all" sacrifice for you (if you are among the elect), the giving of His body for all the chosen. But, no man is born with a hunger for Him or the capacity to decide to seek Him on their own. That is a myth.
