I quite agree that Jesus is present in an invisible manner. That is the same as saying that Jesus is present but his accidents are not.
He is present under the appearances of bread and wine. The bread and wine are not present in their substance, but their accidents remain. Any sense perceptions that we receive are perceptions of the accidents of bread and wine.
And saying “in an invisible manner” applies to just one of the senses: sight. If we are to say the same of all the other accidents we can say that we feel Jesus but in an non-tangible manner, we hear him but in a non-auditory manner. It is all just the same as saying that Jesus is fully present but we can not perceive him. We can not perceive him because his accidents—which are perceptible—are not present. For us to touch Jesus, he would need to be present spatially, but he is not present in a spatial manner.
He is wholly present under the appearances of bread and wine.
It is because he is present in this non-tangible manner that we are able to eat his body and drink his blood.
We receive Jesus Christ, " …Whole and entire…," his Glorified Body, Soul and Divinity. This is the same body which now sits at the right hand of God, in its natural but Glorified mode, as opposed to the Sacramental mode in which He is simultaneously Present in every consecrated Species throughout the whole world. It is the same Body which rose from the dead and walked among the Apostotle and Disciples for forty days, which ate with them, talked with them - and appeared where his wished, at a flash, without being hindered by walls and locked doors, a mode of presence which had absolute power over earthly matter, a Body which, while being visibly present, was not subject to matter.
But in His Eucharistic Presence he is not visible, is he? No, you can’t see him, he is invislble. Nor can you sense his presence by any of your other senses. Why? Because he was catering to our human sensibilities which would be repulsed at the thought that we were consuming his human body, even if it was a Glorified Body. Also, it was because his Sacramental mode of presence demanded that he conform the manner of his presence to the demands of the species and because he wished to be present in every particle of the species that was distributed.
How does He do this? Remember, in his Glorified Person he has absolute power over matter, he can be Present however he wishes, he is not limited by the exigencies of earthly matter, and the species are earthly matter.
How is He present? He is present sacramentally. He is in the species but is not a part of them, nor are they a part of him. Theologians define it this way: the species contain his presence, that is ,they convey his presence, they carry his presence to us. The Council of Trent says that he is under the species. These expressions convey the same meaning. The species are the instruments he uses to convey his presence to us, to " locate " his precence in specific objects, the bread and wine.
Is his presence a material presence, is it a physical presence? Yes, but it is a material and a physical presence which is Glorified, it is no longer earthly matter, it is heavenly matter, a matter that can be " sensed " only if He wishes it to be sensed. Remember there only two things which exist in the universe and in Heaven, material beings and spiritual beings. And Christ, even in his Glorified state, which has been his state of existence since his Resurrection, is a material being as well as a human soul and a Divine Spirit. And it is all of this we receive, but in his Glorified mode of existence.
Do we actually touch Christ when we receive him? Absolutely. How could we consume his flesh and blood if we did not touch him, if he did not touch us? Some have rejected this thought. However, remember that he invited Thomas to " touch " the wounds in his side and in his hands. And this is the exact same body we receive, so we touch him just as Thomas did.
And what does it mean when Trent says we receive Christ, ," Whole and entire…? "
It means just that. We receive Christ just as he appeared to the Apostles after his Resurrection. What they saw, is what we receive. That is what a body is, right? Yes, that’s right, and what did they see? They saw Christ with all his bodily attributes, limbs, hair, clothes, sandles, the works - all his accidents but in a Glorified manner, a manner that in the case of the Eucharist cannot be sensed.
All of this can be gleaned from the simple statements of the Council of Trent which can be read here, chapters 1-4:
