Israel has three different religions, jewish, christianity, and islam. The Islam worship their god Allah. The Christians worship God. And the Jews worship the messiah.
Christians are the followers of Christ, what is commonly called the Church although that word means different things to different sects or Christianity.

That would be to many a type of "idolatry" because we are to worship God, not the followers or the practice of following Him.
Ostensibly, Judaism, Christianity, and Islam worship the same God. However, each ascribes slightly different attributes to His nature.
Christianity is a trinitarian monotheistic religion because it is only worhsipping one God, but the one God in three persons. Each of the three persons is the same in power and in worship, but still only one God.
