A short and plain instruction for the better understanding of the Lord's Supper : With the necessary preparation requir'd: for the benefit of young communicants, and of such as have not well consider'd this Holy Ordinance. To which is annex'd, the office of the Holy Communion. With proper helps and directions, for joining in every part thereof with understanding and benefit. By the Right Reverend Father in God, Thomas, Lord Bishop of Sodor and Man.
