Are Pastors Primarily Facilitators?

One of the principles of church-based training is that, 'Pastors and elders are primarily facilitators in their roles as teachers and overseers.'

The roles of pastor and elder have been divided in various ways based on ecclesiology, but this discussion isn't aimed at that question. Are they primarily facilitators in those roles (regardless of how their roles are defined)? Does the passage in Acts 20 support this? Maybe Ephesians 4?

What about the pastor who says, "My call is to preaching the Word?" Or the elder who says, "I am to oversee the flock." Are they to mainly be facilitators? How do you see it?
