Without getting bogged down in the intricate theology of grace, it should be obvious to every Catholic that God is Infinite Love, and that it was His love that moved him to create man to share in His happiness, and that He loves every soul that He has created with an infinite love and desires its happiness infinitely more than we desire it ourselves.
God created no one to damn them. Every soul that is damned, is damned through its own free choice. "Before man is good and evil, that which he chooses shall be given him". How many saints and spiritual writers tell us that it is precisely this that constitutes one of the principal torments of the damned, seeing how easily they might have saved their soul if only, if only, if only they had responded to God's graces, which they failed to do through their own fault.
It is equally obvious that many souls created by God have lived and died with no knowledge of or contact with His one true Church, with absolutely no possibility of being baptized and belonging to that Church. These souls, too, were created to share in the life of God and to be eternally happy with Him in Heaven. These souls too, will be saved or damned by the choice they freely make.
The conclusion is obvious: The Omnipotent, infinitely merciful and infinitely loving God, is not constrained by the ordinary means that He has established to save souls, namely by being made members of His Church through Baptism, worshipping Him in the Holy Sacrifice of the Mass, frequenting the Sacraments... They will surely be judged on how they have lived according to the natural law and how they have corresponded to the graces God has given them. Who knows if God will not give one or another their own particular revelation with the opportunity to choose for or against Him.
Surely, it is this common sense Catholicism that Fr Cekada was alluding to.
