"All four imams (the founders of the four schools of Islamic law) -- may Allah have mercy upon them -- agree that the apostate whose fall from Islam is beyond doubt -- may Allah forbid it -- must be killed, and his blood must be spilled without reservation. The hypocrite and heretic (zindiq) who poses as a Muslim but has secretly remained an unbeliever must also be killed."

Pius IX, in a letter to the bishops of Italy (10 Aug., 1863), restates this Catholic doctrine: "It is known to Us and to You that they who are in invincible ignorance concerning our religion but observe the natural law . . . and are ready to obey God and lead an honest and righteous life, can, with the help of Divine light and grace, attain to eternal life . . . for God . . . will not allow any one to be eternally punished who is not wilfully guilty" (Denzinger, "Enchir.", n. 1529).
