Adam Clarke on 1 Corinthians 11:2

That ye remember me in all things - It appears that the apostle had previously given them a variety of directions relative to the matters mentioned here; that some had paid strict attention to them, and that others had not; and that contentions and divisions were the consequences, which he here reproves and endeavors to rectify. While Paul and Apollos had preached among them, they had undoubtedly prescribed every thing that was necessary to be observed in the Christian worship: but it is likely that those who joined in idol festivals wished also to introduce something relative to the mode of conducting the idol worship into the Christian assembly, which they might think was an improvement on the apostle's plan.
