I'll just simply ask you the same question I asked my wife last night. Who sets the standard regarding what pagan practices are acceptable and what aren't? Let's say you're right and God would not want to participate in a birthday party because it was somehow rooted in idolatry. Would that same God also participate in a pinata beating party when the pinata also had its roots in idolatry?
I've never known God to be that inconsistent.
Further, in regards to my 'religious convictions' that I want my wife to respect, let's see. She and her religion condemn mine as false, babylonish, says that the cross is pagan and idolatrous, the trinity is false, stain glassed windows depicting Jesus is also idolatrous, etc.. She and they were doing this for years until I began to learn the truth about the 'truth.' Now they just want me to agree to disagree and leave the subject alone.
