You have an interpretation of the meaning but still English words say what they say. The claim is made that the priests have the power. “Priests exercise their power to change bread and wine into the body and blood of Christ by repeating at the Consecration of the Mass the words of Christ: “This is My Body ... this is My blood.”
It clearly says it is by their, the priests’, repetition of certain words that none but a priest can make efficaciously.
Like I said it goes from Merlin with his hand waving and incantations to Hannibal Lecter.
That's a pretty common problem with Catholicism.
Nothing ever says what it says or means what it says.
It means what the Catholic church says it means.
Of course they have the power (Question 355), but the power is not in the incantations but as given to them by Christ (306, 353, 354, CCC 1353). Like I said, learn to read.
