I'm affiliated with the Church of the Nazarene and am currently pursuing a Master of Arts in Pastoral Ministry at Northwest Nazarene University but before that I was apart of the United Methodist Church and knew several Pastors who attended a UMC seminary or a seminary that was approved by the denomination. Where I live in Ohio there are two seminaries which are the Methodist Theological School in Delaware, OH and United Theological Seminary in Dayton, OH. Both have a reputation as being excellent schools and are very good at helping students to prepare for ministry and their provisional member and eventual ordination interviews that will have to undertake. United Theological in particular has a really good program for students which they call their Contextual ministries in which every student is assigned to a group that they have to meet with every semester and they help each other out as well as praying for each other. United Theological I know tends to lean more conservative and MTSO leans more liberal. Outside of the seminaries I've mentioned, I would say that the Duke Divinity School, Garret-Evangelical School, and Asbury Seminary are the best seminaries that someone could attend. Outside of the United Methodist Church, I would highly recommend Indiana Wesleyan University as they are a top-notch school as well.
