Not according to the Catholic Catechism:
1260 "Since Christ died for all, and since all men are in fact called to one and the same destiny, which is divine, we must hold that the Holy Spirit offers to all the possibility of being made partakers, in a way known to God, of the Paschal mystery." Every man who is ignorant of the Gospel of Christ and of his Church, but seeks the truth and does the will of God in accordance with his understanding of it, can be saved. It may be supposed that such persons would have desired Baptism explicitly if they had known its necessity.
THIS TO ALL FREEPERS:
I must sign off, however, I have truly enjoyed this thread. I leave you all with this thought to ponder:
If we , individually, do what the Bible tells us and Trust in the Lord Jesus Christ as our personal Saviour, then we have nothing to fear. WE WILL BE IN HEAVEN IN THE END!
