Know ye not that we shall judge angels? how much more things that pertain to this life? If then ye have judgments of things pertaining to this life, set them to judge who are least esteemed in the church.
I speak to your shame. Is it so, that there is not a wise man among you? no, not one that shall be able to judge between his brethren? But brother goeth to law with brother, and that before the unbelievers.
Now therefore there is utterly a fault among you, because ye go to law one with another. Why do ye not rather take wrong? why do ye not rather [suffer yourselves to] be defrauded? Nay, ye do wrong, and defraud, and that [your] brethren. - I Corinthians 6:1-8

I wonder if the issue of authentic Believer’s would be a factor. Then there are the civil government issues.
Logically, it would be safer to err on the side of Scripture.
