Can a Mute Priest Consecrate the Host?

It’s important to note that the Church encourages the use of sign language at Mass to serve the spiritual needs of the deaf community. But as to whether the form for consecrating the Eucharist (“This is my body . . . This is my blood”) must be spoken or not, the Church has no official position. We’ll have to wait and see if the Church ever makes a decision as to whether a non-spoken language is sufficient for the form of consecration.
