For those down with Missional lingo, sola pastora isn't a new term. However, for those of us just learning, it is the label used for the propensity of many churches to employ (or worse... build themselves upon) a single, charismatic - as in attractive, eloquent, and exciting... not necessarily 'slain in the Spirit' - pastor, usually male.
It is dangerous for one person to have that much responsibility... for the church in general AND for that person specifically. No one can keep all of those plates spinning on their own. Now, don't get me wrong, I am not saying that it is absolutely necessary to have more than one paid staff at a church. In fact, I am not saying it is even necessary to have any paid staff at a church. What I am saying is that the church - local and universal - needs to utilize the concept of the priesthood of all believers. We are each uniquely gifted, and we are each uniquely necessary to accomplish the work of the Kingdom of God.
For too long we have exalted the image of the 'Lone Ranger'. However, we forget that even Mr. Reid (the LR's real name... in the original he had no first name) had Tonto. Well, most actually do remember that. But did you know that the LR's nephew - the son of his brother who was killed by the bandits who also left LR for dead - Dan, and his trusty steed Victor (son of Silver), also helped LR? Also, there was a man who knew LR's secret. It was he who provided LR with all of the silver for his silver bullets.
Okay, now that you know I am an incredible dork... let me reiterate that churches need to move beyond their dependence on a single pastor... heck, beyond their dependence on the professional ministers... and begin to empower the laity for ministry. This is the true function of the pastor, and then to get out of the way... or better yet, join in.
