Holy cow! I had no idea that D&C 20 talked so much about the Book of Mormon & the basic “faith, repentance, baptism, Holy Ghost” principles. Verses 1-36 are all about that. And then it gives direction concerning baptism, and follows that with directions about “elders, priests, teachers” (which is who we were talking about in D&C 42) – plus deacons and members. These directions cover such things as “preach, teach, expound, exhort, and baptize,” of course. Very like the direction given in D&C 42. Even the information about the sacrament is all connected with this basic gospel fourfold. And, the prayers are taken from the Book of Mormon itself. So, D&C 42, the first part at least, seems to be an expansion or further word given right on the heels of D&C 20 (not time-wise, but topic-wise). Fascinating! (I probably should be embarrassed I didn’t know D&C 20 better, but oh well! This is great!)
So, the connection between D&C 20 and D&C 42, eh? Where will I go to learn more about that?
