God thoroughly condemned idolatry throughout both the Old and New Testaments.
I PETER 4:3 For the time past of [our] life may suffice us to have wrought the will of the Gentiles, when we walked in lasciviousness, lusts, excess of wine, revellings, banquetings, and abominable idolatries:
Even Peter who catholics claim was the first pope warns against idolatry. Why does rome continue the practice?
Idolotry is the worship of false Gods. You identify this with the making of images, even images of Christ. Even Jews did not refrain entirely from the making of images, and the early Christians decorated tombs with religious images, even images of Christ. Only Christians who were trying to justify themselves to Jews or ,like the Emperor Leo the Isaurian, to Muslims) would worry about images in churches.
