But here is Paul in I Cor 11:23-29:
"For I received from the Lord what I also handed on to you, that the Lord Jesus, on the night he was handed over, took bread, and, after he had given thanks, broke it and said, “This is my body that is for you. Do this in remembrance of me.” In the same way also the cup, after supper, saying, “This cup is the new covenant in my blood. Do this, as often as you drink it, in remembrance of me.” For as often as you eat this bread and drink the cup, you proclaim the death of the Lord until he comes."
If Jesus was in the bread and in the wine, then He had already come, and would have been coming on a regular basis, unless of course, Jesus was not in the bread and in the wine, but still sitting at His Father's right hand until the time of His second coming. So which was/is it?
I don’t recall seeing much in the way of disquiet or discussion regarding this doctrine amongst the Church Fathers. It really wasn’t until the first millennium that this started to be disputed.
New Advent says that:
Suffice it to say that, besides the Didache (ix, x, xiv), the most ancient Fathers, as Ignatius (Ad. Smyrn., vii; Ad. Ephes., xx; Ad. Philad., iv), Justin (Apol., I, lxvi), Irenæus (Adv. Hær., IV, xvii, 5; IV, xviii, 4; V, ii, 2), Tertullian (De resurrect. carn., viii; De pudic., ix; De orat., xix; De bapt., xvi), and Cyprian (De orat. dom., xviii; De lapsis, xvi), attest without the slightest shadow of a misunderstanding what is the faith of the Church.
We can look at the doctrine of Transubstatation in terms of multilocation of Christ in both Heaven and in uncounted numbers of places upon Earth.
The first, the only mode of presence proper to bodies, is that by virtue of which an object is confined to a determinate portion of space in such wise that its various parts (atoms, molecules, electrons) also occupy their corresponding positions in that space. The second mode of presence, that properly belonging to a spiritual being, requires the substance of a thing to exist in its entirety in the whole of the space, as well as whole and entire in each part of that space. The latter is the soul’s mode of presence in the human body. The distinction made between these two modes of presence is important, inasmuch as in the Eucharist both kinds are found in combination. For, in the first place, there is verified a continuous definitive multilocation, called also replication, which consists in this, that the Body of Christ is totally present in each part of the continuous and as yet unbroken Host and also totally present throughout the whole Host, just as the human soul is present in the body. And precisely this latter analogy from nature gives us an insight into the possibility of the Eucharistic miracle. For if, as has been seen above, Divine omnipotence can in a supernatural manner impart to a body such a spiritual, unextended, spatially uncircumscribed mode of presence, which is natural to the soul as regards the human body, one may well surmise the possibility of Christ’s Eucharistic Body being present in its entirety in the whole Host, and whole and entire in each part thereof.
There is, moreover, the discontinuous multilocation, whereby Christ is present not only in one Host, but in numberless separate Hosts, whether in the ciborium or upon all the altars throughout the world. The intrinsic possibility of discontinuous multilocation seems to be based upon the non-repugnance of continuous multilocation. For the chief difficulty of the latter appears to be that the same Christ is present in two different parts, A and B, of the continuous Host, it being immaterial whether we consider the distant parts A and B joined by the continuous line AB or not. The marvel does not substantially increase, if by reason of the breaking of the Host, the two parts A and B are now completely separated from each other. Nor does it matter how great the distance between the parts may be. Whether or not the fragments of a Host are distant one inch or a thousand miles from one another is altogether immaterial in this consideration; we need not wonder, then, if Catholics adore their Eucharistic Lord at one and the same time in New York, London, and Paris. Finally, mention must be made of mixed multilocation, since Christ with His natural dimensions reigns in heaven, whence he does not depart, and at the same time dwells with His Sacramental Presence in numberless places throughout the world. This third case would be in perfect accordance with the two foregoing, were we per impossible permitted to imagine that Christ were present under the appearances of bread exactly as He is in heaven and that He had relinquished His natural mode of existence. This, however, would be but one more marvel of God’s omnipotence. Hence no contradiction is noticeable in the fact, that Christ retains His natural dimensional relations in heaven and at the same time takes up His abode upon the altars of earth.
There is, furthermore, a fourth kind of multilocation, which, however, has not been realized in the Eucharist, but would be, if Christ’s Body were present in its natural mode of existence both in heaven and on earth. Such a miracle might be assumed to have occurred in the conversion of St. Paul before the gates of Damascus, when Christ in person said.to him: “Saul, Saul, why persecutest thou me?”
We take this all to mean that Jesus is present in the Eucharist as well as in Heaven; His coming again is at the end times and is regardes as different than the ongoing Sacrament that helps to sustain us spiritually through our lives.
By that argument, Jesus is not present with us at all.
