I am surprised that nobody has written to correct an error of your correspondent D. J. Doyle. In a letter attacking Dr. Rung (June 14) he wrote: "A man who possesses the virtue of faith cannot beat the same time in invincible error about the identity of the true Church". This implies that it is impossible for a sincere non-Catholic Christian to possess the virtue of faith. But without the virtue of faith a man cannot be in a state of grace. Therefore, if what Mr. Doyle says is true, everyone in the world who is not a Roman Catholic is in a state of mortal sin. This is a position which no theologian would defend.
May I commend to Mr. Doyle the essay Faith and Dissident Christians in Fr. Charles Davis's book The Study of Theology?
