Ambrose of Milan
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.
He has also well introduced faith, stimulating us to its confession, and to faith itself He has placed virtue as a foundation. For as faith is the incentive to fortitude, so is fortitude the strong support of faith.
