They were not elected but called by Christ. They were not set apart to lord it over the community but to preside over the community with a leadership of charity and love. They were neither better nor worse than others in the community they serve. Pastors who are blind to their own sins cannot serve with compassion and charity. A pastor who thinks of him or herself as better than the congregation cannot shepherd the congregation.
Pastors are human beings.
Set apart through prayer and the laying on of hands they receive the grace or charism to carry out their office. Many Lutherans deny that there is a charism , but without it no mere mortal could fulfil the duties of a pastor. The charism does not make the pastor infallible in his or her teaching, nor does it make the pastor a better person. What we call charism is that special grace given to a pastor to equip him or her for the task of ministry. Recognizing the charism is a way of recognizing that the ministry is not about human authority or ability, but authority granted by God.
