Eusebius of Caesarea
Catena Aurea · Lukasevangelium 12
Also I say unto you, Whosoever shall confess me before men, him shall the Son of man also confess before the angels of God: But he that denieth me before men shall be denied before the angels of God. And whosoever shall speak a word against the Son of man, it shall be forgiven him: but unto him that blasphemeth against the Holy Ghost it shall not be forgiven. And when they bring you unto the synagogues, and unto magistrates, and powers, take ye no thought how or what thing ye shall answer, or what ye shall say: For the Holy Ghost shall teach you in the same hour what ye ought to say.
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 denieth me before men, shall be denied before the Angels of God.
