A significant passage is to be found in the Moralia, Rule XXI., that participation in the Body and Blood of Christ is necessary to eternal life.  John vi. 54, is then quoted.  That no benefit is derived by him who comes to communion without consideration of the method whereby participation of the Body and Blood of Christ is given; and that he who receives unworthily is condemned.  On this John vi. 54 and 62, and 1 Cor. xiii. 27, are quoted. By what method (ποί& 251· λόγῳ) we must eat the Body and drink the Blood of the Lord, in remembrance of the Lord’s obedience unto death, that they who live may no longer live unto themselves, but to Him who died and rose again for them.  In answer, the quotations are Luke xxii. 29, 1 Cor. xi. 23, 2 Cor. v. 14, and 1 Cor. x. 16.
