†. Rom 14:1 . . Him that is weak in the faith receive ye, but not to doubtful disputations.
A strong Bible-based faith consists of the elements of confidence, assurance, conviction, and boldness. A weak faith can be defined as one that's not all that sure whether something is wrong for a Christian; or even that something is right; in other words, a weak faith lacks confidence, assurance, conviction, and boldness.
The koiné Greek word for "doubtful" is dialogismos (dee-al-og-is-mos') which means: discussion; viz: debate.
The word for "disputations" is diakrisis (dee-ak'-ree-sis) which means: judicial estimation.
When somebody begins a statement with the words "in my opinion" they are getting ready to give you their judicial estimation; and since opinions are subject to change, then they inevitably result in debating; which is strictly forbidden within the context of the 14th chapter of Romans.
The issue of tithing is clearly debatable, therefore it falls into the classification of a doubtful disputation.
That said: The rule of thumb for Christians is giving rather than tithing.
†. 2Cor 9:7 . . Every man according as he purposeth in his heart, so let him give; not grudgingly, or of necessity: for God loveth a cheerful giver.
Tithing is not giving; no, it's extraction rather than giving. I don't give the Obama administration my taxes; no, they take it from me by force of law; viz: I pay taxes against my will, both grudgingly and of necessity. That is not the Christian way of giving. We have a faith that works by love, not by law. (Gal 5:6)
Paul labeled Christian giving a grace.
†. Rom 12:6-8 . . Having then gifts differing according to the grace that is given to us, whether prophecy, let us prophesy according to the proportion of faith; Or ministry, let us wait on our ministering: or he that teacheth, on teaching; Or he that exhorteth, on exhortation: he that giveth, let him do it with simplicity
Anyway, back to the 14th of Romans.
Somebody hereabouts suggested that 10% be a baseline. DO NOT DO THAT! It is a gross violation of the principles regulating doubtful disputations. In other words, if you want to set 10% as YOUR baseline okay; but don't you dare attempt to set it for anybody else. That's playing God and usurping the Lord's sovereign prerogative to make the rules for his own church.
†. Rom 14:5 . . Let every man be fully persuaded in his own mind.
That is the golden rule of doubtful disputations; and itself is not debatable. You either comply with it or you fall by it; the choice is yours.
†. 1Cor 10:12 . .Wherefore let him that thinketh he standeth take heed lest he fall.
