Yes, that is so,
- The Encyclical of the Eastern Patriarchs on the Orthodox Faith (as the Confession of Dositheus became more widely known after it was sent to the Anglicans fifty years after its 1672 adoption) states:
“Yet again, we believe that after the sanctification of the bread and wine there remains no longer the bread and wine themselves, but the very Body and Blood of the Lord, under the appearance of bread and wine.” Thus the Lord is in the Eucharist with all His being, and He is in each and every particle, down to the tiniest. He does not depart after the time of Communion, or at any time, so that the Body and Blood revert to their former nature. The Holy Mysteries of the Eucharist should be given the same worship and honor which we would give to the Lord Jesus Christ Himself. "
- This is from the writings of the Greek theologian Dyobouniotes:–
"The belief of the Church is further manifested in the reverence and worship of the Eucharist as such, independently of Communion. The faithful pay worship to the Holy Gifts after they have been consecrated, by virtue of the Presence of our Lord, abiding under the form of bread and wine. This worship belongs to the Consecrated Elements not abstractly but
concretely in their union with the Person of the Word of God.
"As the human nature of our Lord is an object of worship not as regarded in itself, abstractly, but by virtue of the hypostatic union, so the Holy Gifts are worshipped because they are the God-man, His Presence with soul and Divinity, in every particle of the Consecrated Elements.
“The Risen Christ, into whose Body and Blood the Elements are transmuted, never dies, having a spiritual and glorified Body undivided from His Blood. In the Eucharist He is present with all His constituent elements, His soul and His Divinity, Body and Blood undivided.”
- Fr Michael Pomazansky’s “Orthodox Dogmatic Theology” (used as a textbook in some American seminaries):-
"Although the bread and wine are transformed in the Mystery into the Body and Blood of the Lord, He is present in this Mystery with all His being, that is, with His soul and with His very Divinity, which is inseparably united to His humanity.
“… those who receive Communion receive the entire Christ in His being, that is, in His soul and Divinity, as perfect God and perfect man.”
“… to the Holy Mysteries of the Eucharist there should be given the same honour and worship that we are obliged to give to the Lord Jesus Christ Himself.”
