Augustine, a sermon on the Anniversary of his Ordination, sermon ?: “Let me therefore have the assistance of your prayers, that the one who did not disdain to bear with me may also deign to bear my burden with me…Where I’m terrified by what I am for you, I am given comfort by what I am with you. For you I am a bishop, with you, after all, I am a Christian. The first is the name of an office undertaken, the second a name of grace; that one means danger, this one salvation.”
Larry Bean (http://gottesdienstonline.blogspot.com/2015/12/unintended-consequences.html?m=1): Jesus established the vocation of pastor to (among other things) lead public worship. Article 14 of the Augsburg Confession is very clear about the role of the ordained clergy in worship. Just as God has provided specialized vocations in many human endeavors, such as administration, medical care, security, and teaching, He has given us men to lead worship, to preach, teach, and administer sacraments. Does President Ries cede his important administrative duties to undergraduates on certain days of the week? Does the CSP Board of Directors allow students to write critical policies and set budgets? Are students allowed to perform urgent medical procedures on some occasions? Represent the university in delicate court cases? Police the campus? Chair the English Department? But it seems that schools are ever eager to recruit students to ply the pastor's vocation (the one and only one office established by our Lord Himself, a vocation with eternal ramifications) by conducting worship services.
