Collyridians
The collyris was a small cake, distributed by King David at a sacrifice (2 Sam. 6:19 LXX). According to Epiphanius (fourth century), women had imported from Thrace to Arabia a cult-sacrifice to the Virgin Mary, at which a collyris was offered and then eaten by the devotees. Epiphanius objected to women offering sacrifice, holding that while honor is due to Mary, God alone is to be worshiped. The term Theotokos might have stimulated the cult.
