In my experience I have found that there are many denominations that do not require a college education in order to be a Pastor, indeed, many just skip Pastor and go right to Bishop (sounds more impressive). Indeed, all you need to do is find someone to fallow your teaching. Many denominations profess and believe that the Holy Spirit leads the individual rather than the Church to Truth. I believe that if you want to be a Pastor of a church you can simply go out and start one, Your success or failure would depend I suppose on your oral presence or your overall constitution and ability to come across as holy or pious. Some Church shoppers will search and find you and buy what you are selling.
Discipleship however, is something entirely separate from College education, but not in opposition to it. Disciples of Christ who wish to become Sheppards, should fallow the teachings passed on from those who have come before. That is the biblical understanding of discipleship. The discipleship of Christ is different only in the complete commitment of the disciple to the ministry of Christ. To give everything to Christ, renouncing worldly things, renouncing the lust of the Eyes, the Lust of the Flesh and the Pride of life. In the Church started by the apostles, these three principles have grown to Priestly Celibacy, in opposition to the lust of the flesh, the renunciation of luxury and alternately to a life of charity, an opposition to lust of the eyes, and a life of Prayer, which is humility. These three things are in contrast to the fall of Adam. Unfortunately, that church requires more of it's Paster's than just love of Christ, and obedience to these ideals, but an education to to better serve the laity.
It is clear that outside the Catholic Church, just about anything is possible, only your imagination and ability to convince others is required for success. Faith, shaped to the ego, rather than Faith, shaped to humility.
There are more denominations than can be counted that do not require education of the Pastors.
