We stipulate the OT prohibition against idols. We stipulate we have images. We deny that the OT word "idol" fits our images. You fail to show it.
You claim against the ecumenical resolution of the iconoclastic controversy, that we are burdened to show that we are right.
We say that just as the Church was empowered to allow uncircumcised Christians, it is also empowered to allow images. This was all gone over more than 1000 years ago. Your side lost. That doesn't mean you have any standing to restart the debate de novo, and you haven't shown that you have standing.
The problem is that even though there is Biblical precedent for ecumenical councils unfolding doctrine, you want veto power. You are in a position analogous to that of the Judaizers after the Council of Jerusalem.
You claim to follow Scripture. You do not see in Scripture the denial that one can be a Christian without being in the Church.
I suppose that is debatable, but your side does not have a slam dunk on the question.
Says you, a mere man. Scripture is scripture, no denying the word of God.
YOUR church can't allow anything...Your church doesn't even exist in scripture...
We become a member of the Body when we get saved...The 'church' IS the saved...It is NOT an organization empowered to accept or reject anything...
The church of Jesus Christ is spiritual...It's not physical...There are no buildings...
Let me ask you something...Is it your physical body that is a member of your church, or is it your soul???
