Some presbyterian churches have deacons.
They do not differ much. They are very similar to Lutherans, which is extremely similar to Catholicism. Episcopal churches have Deacons and bishops as well as the Pastor, of course. Most episcopal churches are both Catholic and Protestant.
The Pastor.
No protestant churches do not have a single leader like the pope.
Although not named as Deacons in the bible, they were the forerunners of the deacons in todays churches.
There are several types of ordained ministers. In the Catholic faith, ordained ministers can be bishops, priests and deacons. In the Protestant faith, ordained ministers are generally pastors of churches. There are also other ordained ministers within Protestant churches, including youth ministers, assistant ministers and others to minister to the needs of the various groups within the church.
There is no pope of Protestant churches. In fact, you could say that one of the main reasons for the Protestant Reformation was not to have a pope!
These are the ordained church leaders in the protestant Churches. In the Methodist Church, for example, ordained clergy are called ministers, whilst in the Baptist Church they tend to be called pastors. In the Anglican Church, however, the ordained leaders are names the same as the Roman Catholic Church - deacons, priests and bishops.
The founders of many Protestant Churches felt that having statues or pictures of saints in their churches could be regarded as a form of idolatory.
I can't be exhaustive but I know the following denominations have deacons: Roman Catholic Orthodox Christian Churches in the Anglican Communion (Church of England, Episcopal Church, etc). I know there are a handful of protestant denominations that have deacons. Someone else can help out with that.
Protestant, most churches such as Methodist or Baptist come from the protestant faith.
yes
No. Many Protestant and Orthodox churches also name their parishes for saints.
