Thanks for the comments. You seem to be making two separate points.
Regarding the use of a religious authority, I believe your remark requires a clarification on my part. J harbors religious convictions - perhaps I should say schemas or core believes - which leave room for clergy to render decisions enabling certain behaviors which may generally be prohibited if there is a justification for such. Thus, my thought was that if he was told by such an authority that his attempt to uphold the prohibition of masturbation was greatly undermining his ability to lead a productive life in other areas etc. this could be helpful.

your second comment, if I have properly understood it, touches on a significant and basic point, (which has received some attention on this forum), i.e. will the removal of one outlet not create a defensive void for an even more destructive one to assume it's place, as I believe the psychodynamic approach would question much of the work of symptom (or solution) oriented approaches.
