That headline is misleading. In the story, Fr. Corapi says he's suspending his public ministry as a priest, since that is what was demanded of him by his religious superiors. He doesn't say he's 'leaving the priesthood'.
In his youtube announcement he said “once called Father” suggesting he’s leaving the priesthood.

I guess they are ‘misleading’ too?
