● Rom 14:1 . . Accept him whose faith is weak, without passing judgment on disputable matters.
A strong faith consists of the elements of knowledge, confidence, assurance, and conviction. A weak faith can be defined as vacillating; viz: 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 the elements of knowledge, confidence, assurance, and conviction.
Disputable matters are matters of opinion rather than matters of fact. Opinions are often subjective, biased, and arbitrary, rather than objective, unbiased, and by-the book. Opinions inevitably invite perpetual debating that never really gets to the bottom of anything; which, in matters of spiritual significance is strictly forbidden within the context of the 14th chapter of Romans; because debatable matters are not matters of doctrine; but rather; matters of conscience.
We're not talking about black and white doctrines and principles here. Those are not open to debate. We're talking about gray areas.
"Thou shalt not commit adultery" is black and white; while issues like video games, music, fashions, foods, cosmetics, movies, self defense, gambling, swim suits, alcohol, tobacco, firearms, fasting, religious art, crucifixes, couture, and holy days of obligation are debatable. In regards to those areas; let every man be fully persuaded in his own mind rather than somebody else's mind.
Those are things about which each has to decide for themselves according to the dictates of their own conscience; and God forbid they should impose their personal dictates upon others and thus become dictatorial because that's playing God and usurping Christ's sovereign prerogative to make the rules for his own church.
