e sinners." But this is not effected save in as far as
the grace of Christ is made known to them; according to Titus 2:11,
12: "The grace of God our Saviour hath appeared to all men,
instructing us, that denying ungodliness and worldly desires, we
should live soberly, and justly, and godly in this world." Therefore
it seems that Christ's birth should have been made known to all.

Obj. 3: Further, God is most especially inclined to mercy; according
to Ps. 144:9: "His tender mercies are over all His works." But in His
second coming, when He will "judge justices" (Ps. 70:3), He will come
before the eyes of all; according to Matt. 24:27: "As lightning
cometh out of the east, and appeareth even into the west, so shall
also the coming of the Son of Man be." Much more, therefore, should
His first coming, when He was born into the world according to the
flesh, have been made known to all.

_On the contrary,_ It is written (Isa. 45:15): "Thou art a hidden
God, the Holy [Vulg.: 'the God] of Israel, the Saviour." And, again
(Isa. 43:3): "His look was, as it were, hidden and despised."

_I answer that,_ It was unfitting that Christ's birth should be made
known to all men without distinction. First, because this would have
been a hindrance to the redemption of man, which was accomplished by
means of the Cross; for, as it is written (1 Cor. 2:8): "If they had
known it, they would never have crucified the Lord of glory."

Secondly, because this would have lessened the merit of faith, which
He came to offer men as the way to righteousness, according to Rom.
3:22: "The justice of God by faith of Jesus Christ." For if, when
Christ was born, His birth had been made known to all by evident
signs, the very nature of faith would have been destroyed, since it
is "the evidence of things that appear not," as stated, Heb. 11:1.

Thirdly, because thus the reality of His human nature would have come
into doubt. Whence Augustine says (Ep. ad Volusianum cxxxvii): "If He
had not passed through the different stages of age from babyhood to
youth, had neither eaten nor slept, would He not have strengthened an
erroneous opinion, and made it impossible for us to believe that He
had become true man? And while He is doing all things wondrously,
would He have taken away that which He accomplished in mercy?"

Reply Obj. 1: According to the gloss, the words quoted must be
understood of Christ's coming as judge.
