Yes, it was very wrong…

Yes, it was very wrong for others to take their priests and rabbis as ‘gods’ when they changed Halal and Haram, but this same issue is seen when the individual interprets (basically makes up) rulings of the Deen. Thus, the major problem is going against the established indubitable religious rulings, regardless of one’s level in religious studies (and the ability to ‘play games’ based on this).
