Cyril of Alexandria
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.
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.
