To put it bluntly but hopefully effectively, he will not damn them to eternity because water was not poured on their heads.
The above quote is a blatant lie. Pope St. Pius X identified Fr. Fenton in his encyclical; On the Doctrine of Modernists when he said:
"Audacity is their chief characteristic".
God said that unless a man is baptized with water, (having water "poured on his head" while saying the names of the Father, the Son and the Holy Ghost), that he cannot enter the kingdom of God.
The kingdom of God is not only heaven, it is also the Church. Without the sacrament, no one can enter either His Kingdom in this life or in the next. This is so very simple that we learn this and wholly understand it in early childhood.
So according to God, He will damn them because water was not poured on their head. But not so according to Fr. Fenton.
Fr. Fenton makes it all so very, very convenient for the living, but not at all for the dying.
