Luke 12:8

But what will be more glorious than to have the only-begotten Word of God Himself to bear witness in our behalf at the divine judgment, and by His own love to draw forth as a recompense for confession, a declaration upon that soul to whom He bears witness, For not as abiding without him to whom He bears witness, but as dwelling in him and filling him with light, He will give His testimony.

He has also well introduced faith, stimulating us to its confession, and to faith itself He has placed virtue as a foundation. For as faith is the incentive to fortitude, so is fortitude the strong support of faith.

(Hom. 34. in Matt.) The Lord is not then content with an inward faith, but requires an outward confession, urging us to confidence and greater love. And since this is useful for all, He speaks generally, saying, Whosoever shall confess me, &c.

(ubi sup.) Both in condemnation a greater punishment is announced, and in blessing a greater reward; as if He said, Now you confess and deny, but I then, for a far greater recompense of good and evil awaits them in the world to come. There are other modes also of denying which St. Paul describes, saying, They profess that they know God, but in works they deny him. (Tit. 1:16.) And again, If any provide not for his own, and specially for those of his own house, he hath denied the faith, and is worse than an infidel. (1 Tim. 5:8.) Also, Flee from covetousness, which is idolatry. (Col. 3:5.) Since then there are so many modes of denial, it is plain that there are many likewise of confession, which whosoever has practised, shall hear that most blessed voice with which Christ greets all who have confessed Him. But mark the precaution of the words. For in the Greek he says, Whosoever shall confess in Me, showing that not by his own strength, but by the aid of grace from above, a man confesses Christ. But of him who denies, He said not "in Me," but me. For though being destitute of grace he denies, he is nevertheless condemned, because the destitution is owing to him who is forsaken, or he is forsaken for his own fault.

Now Paul says, If thou wilt confess with thy mouth the Lord Jesus, and believe in thy heart that God raised him from the dead, thou shalt be saved. (Rom. 10:9.) The whole mystery of Christ is conveyed in these words. For we must first confess that the Word born of God the Father, that is, the only-begotten Son of His substance, is Lord of all, not as one who had gained His Lordship from without and by stealth, but who is in truth by His nature Lord, as well as the Father. Next we must confess that God raised Him from the dead, who was Himself truly made man, and suffered in the flesh for us; for such He rose from the dead. Whoever then will so confess Christ before men, namely, as God and the Lord, Christ will confess him before the angels of God at that time when He shall descend with the holy angels in the glory of His Father at the end of the world.
