The commandment to do so is in every gospel (check “this is my body”); the Christ abiding in us is a promise of John 15:4; the verse you quote describe the coming of Christ in glory at the end of days but does not negate the completeness of His presence in the Eucharist. We are doing just fine. You?
“the verse you quote describe the coming of Christ in glory at the end of days but does not negate the completeness of His presence in the Eucharist.”
The verses I quoted speak to His present status: (1 Tim.6:15-16), “who is the blessed and only Potentate, the King of kings, and Lord of lords; Who only hath immortality, dwelling in the light which no man can approach unto; whom no man hath seen, nor can see: to whom be honour and power everlasting. Amen.”
He will not become but already is: (Eph. 1:20-22, “Which he wrought in Christ, when he raised him from the dead, and set him at his own right hand in the heavenly places,far above all principality, and power, and might, and dominion, and every name that is named, not only in this world, but also in that which is to come: And hath put all things under his feet, and gave him to be the head over all things to the church,”
John says we don’t know Him completely now: (1 John 3:2), “Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is.”
The bread the cup served in communion are “actualized” memorials of a person and an event.
