“Well, Jesus is full present in the Holy Sacrament of the Altar. “
Afraid not. He is present in you, not the mere Bread and Cup. When that wafer is made, it is not Jesus Christ until a properly ordained man declares it to be so. The wine does not become Jesus’ blood until a properly ordained man declares it to be so.
It’s all dependent on proper credentials as determined by the church. Don’t drag God into it. He is irrelevant.
I don’t think you have a concrete grasp of the concept of transubstantiation. The act of “declaration” neither causes or changes anything. It is not some form of “ritual magic”. As some one once said, you have the emphasis on the wrong sy-LA-ble.
But Christ is God — the second person of the Holy Trinity. I’m not understanding your post at all.
