Babies are not baptized by anyone in a protestant church. A person must one their own free will accept baptism - babies are not able to do that.
Babies are "dedicated" in protestant churches in a baptism type setting. It has no special meaning however is just something the parents are doing to show their appreciation to God for the gift of their child. A minister doesn't have to do it though - anyone can.
As far as marrying people, a pastor doesn't have to do it - its just tradition. A justice of the peace could easily do it.
Clergy have no super powers when in protestant theology. They are regarded as shepards but that's it. Many protestant churches are becoming cultic however and are forgetting this.
In protestant theology pastors are servants just like everyone else and very fallible. To think that any person on this earth has super powers given from God is cultic.
So the miracles Peter worked in God's name made him a cult member?
