For you read that he said: 'God, Who knows the hearts of men, bore witness, giving them the Holy Spirit, even as was given to us; and He made no distinction between us and them, purifying their hearts by faith' (Acts 15:8-9). In which is to be considered, that as Christ is the Cornerstone, Who joined together both peoples into one, so, too, the Holy Spirit made no distinction between the hearts of each people, but united them.

If you are at Rome live in the Roman style; if you are elsewhere live as they live elsewhere.
