I notice you didn't cite the verse or give a quote (again)on this command. And your tone is somewhat accusatory. Something about a holier-than-thou attitude seems to bring out the flippant side of me. Give a verse so I can have some context. It's my bedtime and I'd hate to have us part on a sour note.
2 Thessalonians 2:15
Therefore, brethren, stand fast, and hold the traditions which ye have been taught, whether by word, or our epistle.
