The truth tag was recently removed by me and another user. For the most part, it was used on Truth questions and the tag's existence seems to imply that Truth questions are allowed.
However, in doing so, I came across a few questions that seems like they could have a legitimate use for the tag:
- What does it mean to "worship in truth"?
- What is the Biblical basis that prayer is sufficient as a way to recognize truth?
- https://christianity.stackexchange.com/questions/36020/why-does-jesus-say-very-truly-i-tell-you
The first one admittedly seems like it's primarily opinion based, but I'm not sure, so I've not made a close vote.
The other two are certainly on topic. The second without a doubt. Some might object to the third, but it looks like they just would like an explanation on why a particular phrase is continually stressed in the work, so it might be better on Hermeneutics.
The question in this meta post is that they all seem like they could have a legitimate use of a truth tag. Should we have such a tag despite the pretty much guaranteed misuse of it? If so, what should it be used for and what should the excerpt say?
Update:
I have since created the truth tag with an excerpt almost exactly like the example in bruised reed's answer below. I have added it to questions that appropriately needed it. Most are listed here.
