Supposing an "atheist" is invincibly ignorant that God exists, such ignorance does not supply for the defect of lack of supernatural faith and divine charity. An erring conscience may bind for a time, but it does not excuse in necessary matters. And in the matter of the question of the basic fact of the existence of God, it is so rudimentary, bordering on self-evident, that there could be no practical justifying excuse to deny it. Thus, St. Paul says there is "no excuse" for such persons. The doctrine of invincible ignorance merely means that a person will not be punished for a particular personal sin, it does not mean that they are ipso facto placed in a state that prepares them for salvation; that they are thus translated from a state of sin to the state of justification.
