I find it interesting how the Priest makes him renounce that the Holy Ghost proceeds from the Son. It is my understanding that within the EO they dispute amongst themselves whether or not He actually does proceed from the Son. My understanding is that the problem they actually have with Catholics is the Pope's authority to modify the creed of an Ecuмenical Council. But this is the greater problem of EO: inconsistency of doctrine - but that's what you get when nobody's "in charge".
Scripture condemns this Priest:
John 16:7
But I tell you the truth: it is expedient to you that I go: for if I go not, the Paraclete will not come to you; but if I go, I will send him to you.
Luke 24:49
And I send the promise of my Father upon you: but stay you in the city till you be endued with power from on high.
John 20:22
When he had said this, he breathed on them; and he said to them: Receive ye the Holy Ghost.
