Rather, one must endure all things simply and wholly: those that come from demons, from men, from corrupted nature, and from bodily weaknesses and illnesses.
Perfect patience is the patience that saves a man, as the Lord said: "He who endures to the end shall be saved" (Mt 24:13).
"That you may be perfect and complete, lacking nothing."
Through patience, he says, you must become perfect and complete in faith and love of God, brethren.
According to Saint Maximus, the perfect man is "the one who fights voluntary things, that is, the passions, by self-control, and endures involuntary things by patience in temptations. The complete man is he who practices action with knowledge and contemplation without inactivity."
The cause of perfect work, the Brother of God says below, is Wisdom. For he knows that tested faith and perfect patience in temptations are not the rank of ordinary men, but of those who are wise according to God.
Therefore he next inclines those who desire these two things to ask wisdom from God.
Saint Basil the Great, interpreting "Therefore you shall be perfect" (Mt 5:48), says: "By the image I possess the being of a rational creature. By the likeness I become so by becoming good. Then, according to my power, I become perfect and like God.
"And if, as God is toward me, so merciful also I become toward the brother and neighbor who has sinned against me, by this I am made like God."
