The message projected by that picture reeks of relativism. To the casual observer (or to the poorly catechized, low information Catholic) the message received is that the Cardinal and the female minister are comparable. Go to one or the other for sacraments. What difference does it make?
You may know much more about O’Malley than I do. I posted a “guess”, based on a question I read among the comments and I made an observation.
I read only what was posted at the top of the thread and simply concluded there was no baptism taking place, no sacramentals, nothing of actually Catholic practice involved, but for a priest engaging in a humble in an act of friendship with different believers, some lady.
I do appreciate what you are pointing out also. The action could be interpretated falsely by others, and could mislead other believers about the Sacrament of Holy Orders. I just chose the road for least inflaming, which is probably a first for me. :) Rita.
