Convinced?

"The Catholic Church is convinced that every human being is created in the image of God" -- so pontificate the Bishops of the Church in Indiana: here.  "Convinced" by whom?  And who/what is the referent "Catholic Church" that has been "convinced?"  The metaphysics of the proposition is risible (and shameful).

A more promising intervention by the Bishops might begin as follows:  "The Holy Catholic Church teaches that . . . ."  And might then go on to observe that the salvation of souls depends on it . . . .
