The church of Thyatira is battling a particular prophetess with much satanic influence. Effectually, they are consenting to her crafts by suffering her a place in their community/congregation. The Lord is dealing with her in His own way. He is asking them to beware and resist her and those that are bedding with her (consenting/allowing to her doctrine) by holding fast to the faith.
