The “World-Wide Web” is, in fact, world wide. When you post stuff, other people may well read it. There are some implications to this.
1. You may well be a seminarian and have taken an intro course in liturgy or New Testament. That’s great. But, in your haste to show off your new-found knowledge remember that there are people who have taken a hell of a lot more courses and read a hell of a lot more sources in the original languages than you.
2. I’ve done a lot of work in my field. I have a BA, an MDiv, an STM, and am a few pesky chapters away from my PhD all focused in my area. This means that I’ve read so much that I have a really good idea of how much about my field I don’t know!! True depth of learning breeds humility.
3. Don’t assume anything simply because you’re going to be clergy. There are laity who have forgotten more about liturgy—and a host of other topics—than you will ever know. And not all of them have “Dr.” in front of their names, either.
4. If you make major factual errors, be prepared to be called on it and furthermore be willing to accept correction. See above on humility… If you don’t feel that way, that’s fine—either don’t post things publicly or prepared to be dismissed.
