“The Son therefore goes on to say: ‘Those that You gave me, I have kept, and none of them is lost, but the son of perdition;’ that the Scripture might be fulfilled. The betrayer of Christ was called the son of perdition, as foreordained to perdition, according to the Scripture, where it is specially prophesied of him in the 109th Psalm.”—Saint Augustine
