To Mask or Not to Mask?

[1 Corinthians 11:4] When a man prays or preaches, if he covers his head, he humiliates his head.

 [1 Corinthians 11:5] When a woman prays or preaches, if she does not cover her head, she humiliates her head, because it is like having her hair shaven.

 [1 Corinthians 11:7] A man should not cover his head because he is the image and glory of God; but a woman is the glory of a man.

First of all, this is just one of the minor topics of Pauline contextualised or dispensational ethics, it's by no means having the same status as Christ's commandment [entole], not to mention the Law [Nomos].

Biblical Greek Κατακαλύτομαι

 Katakaluvptomai, means wearing a veil, which is now can mean a mask. Yet, the question of wearing a mask or not nowadays, under contemporary complex social and public health subjects surely has multi-facets to discuss, and it's impossible to discuss them all.

The main reason Paul told men in churches then not to cover their heads,  is to separate them from the local fornication culture at that time.  Because many men at that time covered their heads and went to the temples to find gentile temple prostitutes, which is the specific kind of prostitution prohibited by the Law. Furthermore, there were no protection measures at that time.  These were sort of like 'committing suicide' and could had much higher chance of creating plagues!

He asked women to cover their heads at meeting could be due to men in the area then were generally uncivilised and some women could have attracted people to commit adultery. Paul did not want to let the church step on the road of fornication culture as in the gentile temples then.  He didn't want something as shameful or defiling as that to happen in the churches.  Although the number of Christians grew rapidly at that time, they were still minority in the population.  Thus they need to protect themselves and be "sanctified".

When Paul said these words, he was also dealing with the management of faith culture at that time, and he did not regard these ideas as Law[Nomos].

The so-called head covering culture mentioned in the Old Testament, according to the original Hebrew text, was the kind that covered or almost covered the whole body. They were related to shamefulness. And, they were not law too.
