Also I say unto you, Whosoever shall confess me before men, him shall the Son of man also confess before the angels of God:
All Commentaries on Luke 12:8 Go To Luke 12
Eusebius of Caesarea
AD 339
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. But having confirmed them with good hope by so great promises, He again rouses them by more alarming threats, saying, But he that denies me before men, shall be denied before the Angels of God.
He rightly declares this threatening, in order that none should refuse to confess Him by reason of the punishment, which is to be denied by the Son of God, to be disowned by Wisdom, to fall away from life, to be deprived of light, and to lose every blessing; but all these things to suffer before God the Father who is in heaven, and the Angels of God.
