I think it's more complicated than that, because "Protestantism" is so broad. Certainly it is the case that the older, more mainstream, and upper-class denominations have a high emphasis on educated clergy. Most Lutheran denominations will not permit member congregations to call pastoral candidates who have not completed seminary. In the mid twentieth century, Methodist leadership insisted that pastors be fluent in German or French, so as to be able to keep up on current trends in theology in Europe without having to wait for translations. Presbyterians by and large have a highly educated laity, and so their clergy must be similarly educated to hold the respect of the congregation. However, "low church" Protestantism does not have the same notions of education; some even ridicule seminary training as antithetical to genuine ministry. Here, the emphasis on "calling" (which pervades all of Protestantism and also Catholicism) tends to point to those who are charismatic, either dynamic orators or highly magnetic easy-to-like people. You find this among Pentecostal denominations, but also in some of the Baptist groups, more conservative and older Methodist congregations, independent/fundamentalist churches, and newer Charismatic denominations such as Vineyard and Foursquare. Not all of these eschew education, but all do downplay it. What matters here is not so much that the preacher/pastor/teacher is well-schooled, but that he (or she, and so throughout, although not all Protestant denominations recognize female clergy) has a divine call and the gifts necessary to do the job.M.J. Young, I should have used “Pastor” instead of “Minister.” I forgot the wide variety of Ministry, and thank you for reminding me. I think the basic point still stands. The average Protestant pastor is a spiritual leader to their congregation. The authority of their leadership comes from their knowledge of the Bible and Christian theology, certified by a seminary or their denomination. If this is incorrect, please let me know.
Much of what you say about Catholic priests seems accurate to me (I am not Catholic, but do have more than passing knowledge of the beliefs). What you say of Pastors is more applicable to Rabbis. The reason a Pastor believes he can tell you the right way to live is because he has been called and sent by God to serve in a particular service role in the lives of his congregation. Understanding scripture is an important part of this, but it is the secondary part. Hearing from God is the more fundamental part. Protestants believe that all Christians have this connection to God, but that Pastors are particularly gifted in knowing how to help other Christians find God's will for them.The reason a Pastor believes they can tell you the right way to live is because they have studied Christian belief. The reason a Priest believes they can tell you how to live is because the have inherited the special authority of the Apostles.
