Communion

Watson's Biblical & Theological Dictionary

in a religious sense, refers chiefly to the admission of persons to the Lord's Supper. This is said to be open, when all are admitted who apply, as in the Church of England; to be strict, when confined to the members of a single society, or, at least, to members of the same denomination; and it is mixed, when persons are admitted from societies of different denominations, on the profession of their faith, and evidence of their piety. The principal difficulty on this point arises between the strict Baptists and Paedo-Baptists.
