Depending on how or when you observe, from tomorrow or this weekend’s last Scripture reading:
Note those verbs in the Christian’s mission statement: go, make, baptize, teach. I suppose each of us would have a particular expertise. And I mean that as a quality separate from canonical justifications. The Alleluia verse narrows it down:
Go and teach all nations, says the Lord;
I am with you always, until the end of the world.
Go and teach here.
