We are surrounded by idolatry in many forms. I've been seeking to understand different groups within the church and what I've learned is how ignorant I have been about the whys and what they actually believe and teach. There are many straw man arguments and people talking past each other. I've have ended up being encouraged by how much we have in common instead of what we disagree on. I think each church tradition and denomination could learn from others if they would pray for humility and prioritize what Jesus commanded. That we love one another.
I visited an Orthodox church as a protestant and asked them about the icons. It was interesting and as a protestant while we don't have icons I see plenty of idolatry around me. We can make almost anything into an idol. The big oversight for me was that for centuries most people were illiterate and only had the church. Not only did they not have direct access to the Scriptures but they couldn't read them even if they had access.
I'm not excusing abuses or things I disagree with within the churches but it helps to understand by asking the people you disagree with and disagree in good faith and love. I think Christians are responsible for turning people away from Christ when we fight and act in anger and hate towards others. Its incredibly sad. Not saying we should devalue truth, but some of us can make it an idol and forget love. We should hold both. The truth in love.
Stay humble. Love the brothers and sisters.
