You are so proud of your scholarship ? You want to do what Christ himself told you to do ? Then go back to Mathew 28 and its surrounding context and do some exegesis in the Greek (which scholars are so proud of) Does it say to build church buildings, and million dollar satellite churches, actually NO ! It doesn’t. Does Jesus the Saviour ask you to build 6 million dollar churches ? No it doesn’t ! Does it ask you to provide a church meeting more “consumer friendly” or a homogeneous (white like us !, or perhaps black like us !, or perhaps Chinese like us !) fresh “church plant” ? No it doesn’t. Where is the emphasis in the New Testament ? Answer: Preaching the gospel “to the sick”, taking care of widows and orphans, using your own money (and/or possessions) to help those who have nothing, and visiting those in prison and giving them food and Jesus’s hope (because in ancient times there was no obligation to even feed a prisoner. The food kept them from dying, invisible) For those of you who are slow “getting it” Jesus says in Matthew 28, “teaching them ALL THE THINGS I TAUGHT YOU, (implied, over the last three years AS I LIVED WITH YOU) (Read the gospels to find out what that was !) and teaching other faithful men (and women, implied) NOT ONLY THAT ! but teach them how to teach THAT to others, MAKING DISCIPLES. It is NOT about wanting to get more people into YOUR Church “to raise weekly numbers !” WHO told you it is It is Jesus’s CHURCH, fool ! That is addition. With that strategy Islam will eventually overwhelm the church. Jesus talked about multiplication! NOW, I am not going to finish the “book or lecture ” here; but HERE IS THE CHALLENGE: Paul LOVES military analogies. Are you going to OBEY your superior, or are you going to “wing it” as the ancient Frank Sinatra suggested ?

I am not and have never been a paid pastor. My day job is a non-church professional role in IT working for a large multi-national company.
My ministry work is motivated by my passion for the Gospel and the people I serve.

Possible purposes of a sermon: comfort people who are sorrowing; tell people that God loves them; remind people of the importance of community; build up people in their walk of faith; bring hope or joy or peace; encourage people in the midst of despair; teach the Bible.
What separates this list from “just teach the Bible” is that most of these goals are not pedagogical. You are correct (imho), monologue is not a good pedagogical technique. But monologues are good for other things, and a well-prepared and well-delivered sermon can accomplish some of these other things. If our major purpose is pedagogy, then yes we should stop preaching. But every week I get up there and, using the Bible in a variety of ways, I try to help people make sense of their lives and the world around them. And I know that monologues are one way to do this.
Having said this, i also need to say that I agree with most of your initial argument. Seminaries are not doing a good job of preparing people for the various tasks of being a pastor, and furthermore we need to rethink this whole concept of church from within our local context.

To your original premise, I am in full agreement with that leaning, but I am convinced that the failure of the church to transform as needed is due to its primary control of the church “system” by those who fit best with the “system” as it has become, those who fulfill the pastor and teacher gifted roles, not necessarily offices, and the expulsion or exit of the evangelistic, and apostolic roles that are calling for something new. See Curt Watke’s APEPT profile. Of course, I am operating out of my prophetic role here (how to make thing better). I am grateful to you for your role in calling for change. And, as we all know, change is usually slow if it comes at all.

BTW-I came to the pulpit after a US Coast Guard 29 year career and after owning my own business, which I mention because I try to bring this background to bear when leading the flock.

This may simply be a reflection of my personal learning style, but I have found spending time with others who are actively seeking to be faithful to the call of Christ and exploring together what that might mean for each of us, to be the most helpful.
Of course this can take a variety of forms and one might rightly call this activity ‘church’.

For me it comes down to the direction and intent of the getting together. Our motives become more apparent as we go along and we need ongoing ‘reformation’ and re-callibrating… of our values and desires (perhaps more than visionary stuff).

As I write this, I am aware that I resist the notion of a visionary leader partly because they often create more passive followers. I suspect Jesus would not have passed as a visionary leader. His PR strategies were clumsy and inconsistent.

I wonder what we are hoping for in leaders in this day.

I am helped by others who empower me with skills/understanding/permission/support/modelling.
That is the kind of leadership I’m most interested to see.
