Which churches have regarded the Athanasian Creed as authoritative?

The Athanasian Creed is regarded as authoritative in the Roman Catholic and some Protestant churches. While it has received some recognition in the East, this has been limited to the period since the 16th century. Its liturgical use has declined in recent centuries, partly due to its nature as a theological exposition rather than a creed and its inclusion of "damnatory clauses" that assert salvation is only for those who accept every detail of its teaching.12
