Craig, my view is that Paul is talking to Timothy about a variety of issues affecting daily life. This would cover behavior in Christian meetings, in homes, and everywhere. I get this because of this verse….

3:14 These things I write to you, though I hope to come to you shortly; 15 but if I am delayed, I write so that you may know how you ought to conduct yourself in the house of God, which is the church of the living God, the pillar and ground of the truth.

The house of God, the outcalled of the living God, is comprised of the body of believers. It is not a place but a people. And we need to know how to conduct ourselves where ever we go because we ARE the temple(s) of God. He resides in us.
