When I go to Rome, I fast on Saturday, but in Milan I do not. Do you also follow the custom of whatever church you attend, if you do not want to give or receive scandal.
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.
Ambrose... the Apostle Paul says that we are sealed in the Spirit (cf. Eph. 1:13); since we have in the Son the image of the Father, and in the Spirit the seal of the Son. Let us, then, sealed by this Trinity, take more diligent heed, lest either levity of character or the deceit of any unfaithfulness unseal the pledge which we have received in our hearts.
