Ad Episcopos Aegypti et Libyae

All things whatsoever our Lord and Saviour Jesus Christ, as Luke wrote, ‘both has done and taught,’ He effected after having appeared for our salvation; for He came, as John says, ‘not to condemn the world, but that the world through Him might be saved.’ And among the rest we have especially to admire this instance of His goodness, that He was not silent concerning those who should fight against us, but plainly told us beforehand, that, when those things should come to pass, we might straightway be found with minds established by His teaching. For He said, ‘There shall arise false prophets and false Christs, and shall show great signs and wonders; insomuch that, if it were possible, the very elect shall be deceived. Behold, I have told you before.’ Manifold indeed and beyond human conception are the instructions and gifts of grace which He has laid up in us; as the pattern of heavenly conversation, power against demons, the adoption of sons, and that exceeding great and singular grace, the knowledge of the Father and of the Word Himself, and the gift of the Holy Ghost. But the mind of man is prone to evil exceedingly; moreover, our adversary the devil, envying us the possession of such great blessings, goes about seeking to snatch away the seed of the word which is sown within us. Wherefore as if by His prophetic warnings He would seal up His instructions in our hearts as His own peculiar treasure, the Lord said, ‘Take heed that no man deceive you: for many shall come in My name, saying, I am he; and the time draws near; and they shall deceive many: go ye not therefore after them.’ This is a great gift which the Word has bestowed upon us, that we should not be deceived by appearances, but that, howsoever these things are concealed, we should all the more distinguish them by the grace of the Spirit. For whereas the inventor of wickedness and great spirit of evil, the devil, is utterly hateful, and as soon as he shows himself is rejected of all men — as a serpent, as a dragon, as a lion seeking whom he may seize upon and devour — therefore he conceals and covers what he really is, and craftily personates that Name which all men desire, so that deceiving by a false appearance, he may thenceforth fix fast in his own chains those whom he has led astray. And as if one that desired to kidnap the children of others during the absence of their parents, should personate their appearance, and so putting a cheat on the affections of the offspring, should carry them far away and destroy them; in like manner this evil and wily spirit the devil, having no confidence in himself, and knowing the love which men bear to the truth, personates its appearance, and so spreads his own poison among those that follow after him.
