Romans 14

One of the purposes of conferences in the Church is to give the members an opportunity to sustain their leaders.  Paul provided the saints in his day counsel on sustaining and following their leaders writing -

"LET every soul be subject unto the higher powers. For there is no power but of God: the powers that be are ordained of God.
2 Whosoever therefore resisteth the power, resisteth the ordinance of God: and they that resist shall receive to themselves damnation.
3 For rulers are not a terror to good works, but to the evil. Wilt thou then not be afraid of the power? do that which is good, and thou shalt have praise of the same:
4 For he is the minister of God to thee for good. But if thou do that which is evil, be afraid; for he beareth not the sword in vain: for he is the minister of God, a revenger to execute wrath upon him that doeth evil.
5 Wherefore ye must needs be subject, not only for wrath, but also for conscience sake."  (New Testament | Romans 13:1 - 5)

At the same time, Paul counsels the Romans to be very careful of disputations or offending others over minor, insignificant things (especially those saints that are opinionated) for -

"HIM that is weak in the faith receive ye, but not to doubtful disputations."  (New Testament | Romans 14:1)

In other words, be very careful about demeaning eating habits, drinking habits, lifestyles, etc. where one may feel it important for them (thereby their own personal commandment) and another that does not that is not directly in violation of the commandments.  For example, a Jew may still feel it of great importance to live the eating habits of the Mosaic law (done away with in Christ) where new Roman converts may not.  Paul wisely counseled -

"Let us not therefore judge one another any more: but judge this rather, that no man put a stumblingblock or an occasion to fall in his brother's way."  (New Testament | Romans 14:13)

Which would suggest at the same time, we must be careful when amongst individuals that feel strongly about a personal law that we don't offend for -

"It is good neither to eat flesh, nor to drink wine, nor any thing whereby thy brother stumbleth, or is offended, or is made weak."  (New Testament | Romans 14:21)
