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.

When I am at Rome, I fast on a Saturday: when I am at Milan I do not. Do the same. Follow the custom of the church where you are.

If you are at Rome live in the Roman style; if you are elsewhere live as they live elsewhere. [Lat., Si fueris Romae, Romano vivito more; Si fueris alibi, vivito sicut ibi.]

When in Rome, live as the Romans do; when elsewhere, live as they live elsewhere.

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.

A duty is to be chosen from what is virtuous, and from what is useful, and also from the comparison of the two, one with the other; but nothing is recognized by Christians as virtuous or useful which is not helpful to the future life.
