Idolatry was outlawed by the church.

Idolatry is the worship of 'idols' or false gods.

No, Catholics do not commit idolatry. Catholics worship only God.

Of course not. Jesus went to the Temple and as a young Jewish boy He would have been taught there by the Rabbis. Do you not think He studied? Idolatry is making something more important than God, or putting it in the place of God. If you are doing that, then it is idolatry. But simply studying is not idolatry.
