Well...let me put it this way..
The Ten Commandments stated that you should worship God and only God. So, If you worshiped God while your friend worships something else, then i guess it's ok.
BUT If you worship what your friend is worshiping, then obviously you are worshiping false idols....that is if ,say, you are a christian

Most people choose to worship separately because there is a comfort zone that all in that church, synagogue, or mosque are of like mind. If a person comes to understand or believe that those from different faiths are ALL saying prayers to the same Creator, irrespective of what the Creator might be called in different languages or religions (e.g., God, Allah, Vishnu, etc.), then there is no harm in interfaith worship. The only things that would differ are the manmade rituals involved with each.

There are some who would say that the various tribal and indigenous religions worship the devil but do not know they are. Either way, very few members of these types of religions would purposefully worship the devil but there are probably some that would just like there are for any other culture.
