JEROME . Not that Peter was of a different speech or nation, but a Hebrew as his accusers were; but every province and every district has its peculiarities, and he could not disguise his native pronunciation.
REMIGIUS . Observe how baneful are communications with evil men; they even drove Peter to deny the Lord whom he had before confessed to be the Son of God.
RABANUS . Observe, that he said the first time, I know not what thou sayest; the second time, He denied with an oath; the third time, He began to curse and to swear that he knew not the man. For to persevere in sinning increases sinfulness, and he who disregards light sins, falls into greater.
REMIGIUS . Spiritually; By Peter’s denial before the cock-crow, are denoted those who before Christ’s resurrection did not believe Him to be God, being perplexed by His death. In his denial after the first cock-crow, are denoted those who are in error concerning both Christ’s natures, His human and divine. By the first handmaid is signified desire; by the second, carnal delight; by them that stood by, the dæmons; for by them men are led to a denial of Christ.
ORIGEN . Or, By the first handmaid is understood the Synagogue of the Jews, which oft compelled the faithful to deny; by the second, the congregations of the Gentiles, who even persecuted the Christians; they that stood in the hall signify the ministers of divers heresies, who also compel men to deny the truth of Christ.
AUGUSTINE . (Quæst. Ev. i. 45.) Also Peter thrice denied, because heretical error concerning Christ is limited to three kinds; they are in error respecting His divinity, His humanity, or both.
RABANUS . After the third denial comes the cock-crow; by which we may understand a Doctor of the Church who with chiding rouses the slumbering, saying, Awake, ye righteous, and sin not. (1 Cor. 15:14.) Thus Holy Scripture uses to denote the merit of divers cases1 by fixed periods, as Peter sinned at midnight and repented at cock-crow.
JEROME . In another Gospel we read, that after Peter’s denial and the cock-crow, the Saviour looked upon Peter, (Luke 22:61.) and by His look called forth those bitter tears; for it might not be that he on whom the Light of the world had looked should continue in the darkness of denial, wherefore, he went out, and wept bitterly. For he could not do penitence sitting in Caiaphas’ hall, but went forth from the assembly of the wicked, that he might wash away in bitter tears the pollution of his timid denial.
LEO . (Serm. 60. 4.) Blessed tears, O holy Apostle, which had the virtue of holy Baptism in washing off the sin of thy denial. The right hand of the Lord Jesus Christ was with thee to hold thee up before thou wast quite thrown down, and in the midst of thy perilous fall, thou receivedst strength to stand. The Rock quickly returned to its stability, recovering so great fortitude, that he who in Christ’s passion had quailed, should endure his own subsequent suffering with fearlessness and constancy.
