The Synod of Laodicea (c. 363 AD)

Christians, when they attend weddings, must not join in wanton dances, but modestly dine or breakfast, as is becoming to Christians.

Ancient Epitome of Canon LIII.

It is unsuitable to dance or leap at weddings.

This canon does not call for explanation but for reflexion, and greatly it is to be desired that it should be observed by Christians, and that through like improprieties, wedding-days, which should be days of holy joy and blessing, be not turned, even to the bride and groom themselves, into days of cursing. Moreover the Synod of Trent admonishes bishops to take care that at weddings there be only that which is modest and proper.
