It has not been given to others. To His Church, His mystical bride, Christ has given all graces. No grace in the world, no grace in the history of humanity is distributed except through her. No, it would be a second error to think that. Those who cry for intolerance in interpreting St. Cyprian's formula, Outside the Church there is no salvation, also reject the Creed, I confess one baptism for the remission of sins, and are insufficiently instructed as to what baptism is.
Baptism of desire can be explicit .
Many times in Africa I heard one of our catechumens say to me, Father, baptize me straightaway because if I die before you come again, I shall go to hell. I told him No, if you have no mortal sin on your conscience and if you desire baptism, then you already have the grace in you. The doctrine of the Church also recognizes implicit baptism of desire. This consists in doing the will of God. God knows all men and He knows that amongst Protestants, Muslims, Buddhists and in the whole of humanity there are men of good will.
