As you may or may not know, the Catholic clergy has a long vested interest in (ceremonial) baptism.  That interest is both financial and dogmatic.  Furthermore, that vested interest has been employed coercively, as in the hierical position on infant baptism, and much much more.  That's why, for starters!  Perhaps you recognize here the practical and dogmatic thrust of church reformers, then  (16th century) and now, and all points in-between!
