[John Leland 1789]

Is the pastor the only person who can council people? In a very large church, there are often counseling ministries designated for that purpose.

Well, that's assuming you would pastor "a very large church," and have other capable people for that purpose.

What if you have a smaller congregation?

I agree that a smaller congregation poses more of a challenge. Though even a small church could have some competent lay couples to help out in that area, or partner with other churches/ministries.
