No one would argue that the two denominations are known for completely different styles. Lutherans have been wary of church hierarchy since Martin Luther tried to reform it in the early 1500s. He saw renegade priests selling tickets to heaven, fathering families despite their vow of celibacy, holding property against church rules. He concluded that man-made institutions, including church governments, are not to be trusted. Only pastors are ordained in the Lutheran church.
Bishops have more power than priests, priests rank higher than deacons.
We need to reexamine how the church is led. He won't accept the Episcopal blessing now required for new Lutheran ministers. And he is prepared to leave his denomination. God will take care of me. Where I end up will be God's work.
