All of these Scriptures clearly are worthy of being honored by heeding them and performing them as one is led by the Holy Spirit of God.
What is not clear is what you are intending to accomplish by posting these particular pieces of Scripture on this forum. as opposed to ANYTHING from the Holy Bible.
I was responding to a post by Elsie (post #437) that quotes yet other texts.
The general theme of this subthread concerns how to post in the Religion Forum. A running theme in other threads (as well as this one) is that we readers are exhorted to go to the Bible for truth and guidance. Accordingly, over time I reviewed the New Testament letters concerning speech and related matters.
The quotation from Matthew 23 is not the Bible's only guidance on speech or writing. This quotation, in conjunction with other things in the Bible, would establish that using "you hypocrites" isn't absolutely sinful, but other scriptural evidence makes me wonder just how often Christians are called to follow this particular example.
(Even if you readers don't believe that calling others "you fool" may put you in spiritual danger--see Matthew 5:22--calling people "fools" may lead to other problems. I don't advise readers to try it very often, whether on this forum or in real life.)
In looking up 1 Corinthians 11:1 just now, I found yet another text that I missed earlier:
[1 Corinthians 10:31] Whether therefore ye eat, or drink, or whatsoever ye do, do all to the glory of God.
[32] Give none offence, neither to the Jews, nor to the Gentiles, nor to the church of God:
[33] Even as I please all men in all things, not seeking mine own profit, but the profit of many, that they may be saved.
[11:1] Be ye followers of me, even as I also am of Christ.
(At least a few newer translations place these verses together in one paragraph. I am aware that these chapter-and-verse and paragraph divisions, while useful for some purposes, are not part of the original text--and no large mainstream group, I think, considers these divisions inspired.)
I also have apparently different ideas about the quotations from Mark and Galatians. Though extensive discussion of these ideas may be a bit off-topic, the gist is that Mark 7 may contain more of a "test" than an insult, and Galatians 5:12 strikes me as something rhetorically interesting in its context, something more than an actual "wish" (and more than even what I'll call a rhetorical wish) that certain people mutilate themselves.
