If you believe a chair is God, you are very confused.
If you believe the chair is or represents a god (to wit not God), then yes it is an idol.
And that’s the problem: praying to someone/thing other than God.
Thanks for your reply.
Correct me if I’m wrong, but your answer is in the affirmative: In the example, if I believe the chair is God, it is an idol; if not, then no.
Would that be correct?
