We should know that there are three modes of temptation; suggestion, delight, and consent; and we when we are tempted commonly fall into delight or consent, because being born of the sin of the flesh, we bear with us whence we afford strength for the contest; but God who incarnate in the Virgin’s womb came into the world without sin, carried within Him nothing of a contrary nature. He could then be tempted by suggestion; but the delight of sin never gnawed His soul, and therefore all that temptation of the Devil was without not within Him.
