8 And after all these things, He still receives His murderers, if they will be converted and come to Him; and with a saving patience, He who is benignant to preserve, closes His Church to none. Those adversaries, those blasphemers, those who were always enemies to His name, if they repent of their sin, if they acknowledge the crime committed, He receives, not only to the pardon of their sin, but to the reward of the heavenly kingdom. What can be said more patient, what more merciful? Even he is made alive by Christ's blood who has shed Christ's blood. Such and so great is the patience of Christ; and had it not been such and so great, the Church would never have possessed Paul as an apostle.
