Cant Christianity be considered Idolatry?

I dont mean to offend anyone. Specifically Catholics, you believe in the father, the son, and the holy ghost. Christians in general worship Jesus as their saviour. The other religions, Islam and Judaism, worship the one God, while recognizing their prophets, Muhammad, Moses, etc. They consider them prophets but they dont pray to them and dont consider them "saviors of mankind" rather just messengers of a higher power. SO cant Christianity therefore, in some way, be considered idolatry?
