Yes, Acts 14:23: "So when they had appointed elders in every church, and prayed with fasting, they commended them to the Lord in whom they had believed."Is there anything in Acts that teaches us to pray to icons or that there was such as thing as a priesthood in the Apostle's church government? Because the Church in Acts didn't do those things.
Elders are priests, and they are appointed by the apostles who are the first bishops.
Icons are mentioned several times in the Old testament, including the angelic sculptures made by Moses. The Church has always made the final decision on controversies like icons through councils, as I cited earlier in Acts 15. What we don't do is separate from the very Church guided by the Holy Spirit since it's inception at Pentecost, as through the councils He guides us to the right decision.
