When I am at Rome I fast as the Romans do; when I am at Milan I do not fast. So likewise you, whatever church you come to, observe the custom of the place, if you would neither give offence to others, nor take offence from them.
AmbroseAs the print of the seal on the wax is the express image of the seal itself, so Christ is the express image - the perfect representation of God.
Ambrose... the Lord Jesus said, 'To those who are in bonds, Come out, and to those who are in prison, Go forth' (Isa. 49:9); so your sins are forgiven. All, then, are forgiven, nor is there any one whom He has not loosed. For thus it is written, that He has forgiven 'all transgressions, doing away with the handwriting of the ordinance that was against us' (Col. 2:13-14). Why, then, do we hold the bonds of others, while we enjoy our own remission? He, who forgave all, required of all that what every one remembers to have been forgiven to himself, he also should forgive others.
AmbroseWe ask for what reason our Lord was unwilling to state the time of His coming (cf. Mk. 13:31-32). If we ask it, we shall not find it is owing to ignorance, but to wisdom. For it was not to our advantage to know; in order that we being ignorant of the actual moments of judgment to come, might ever be as it were on guard, and set on the watch-tower of virtue, and so avoid the habits of sin; lest the day of the Lord should come upon us in the midst of our wickedness.
AmbroseRemember, then, that you received a spiritual seal, the spirit of wisdom and understanding, the spirit of knowledge and reverence, the spirit of holy fear. Keep safe what you received. God the Father sealed you, Christ the Lord strengthened you and sent the Spirit into your hearts as the pledge of what is to come.
