Should who administer baptism?
Baptism in the Orthodox Church is administered only by the clergy. But our Protestant brethren do not, at all, accept human Priesthood. So in their churches, a minister and not a clergyman administer baptism. He could be an elder (or a lady elder in case of groups who allow women ministers). Anyhow, according to the Protestant belief, the elders or the ministers are not clergymen.
