I don't know if this is the right place to ask this question, but here goes:
From what I've read, the West considers the "words of consecration", to be the moment when the bread and wine become the Body, Blood, Soul and Divinity of Christ; but the East considers the "epiclesis" to be the moment of change.
As Byzantine Catholics, what is your take? I ask because I've also read that the West at one point in history didn't have the 'epiclesis'. Is this true? If the 'epiclesis' is missing, does the change not occur?
Thanks!
