I have an honest question about elders (or pastors, if you prefer). (“Honest” means that I’m actually asking for answers…)

For most of my life (including today), I have heard something like this: “Elders (pastors) are responsible for the teaching/preaching ministry of the church.”

Sometimes, I hear it this way: “The senior pastor is responsible for the teaching/preaching ministry of the church.”

Now, in context, the statement usually means (at least) teaching/preaching to the congregation once per week (usually more often).

But, here’s my honest question: Can this position be justified from Scripture? If so, how?

Like I said, this is an honest question. I would appreciate comments in answer to this question (these questions), especially from those who agree with the positions stated above.
