In My Opinion
I appeal to you, brothers, by the name of our Lord Jesus Christ, that all of you agree, and that there be no divisions among you, but that you be united in the same mind and the same judgment. For it has been reported to me by Chloe's people that there is quarreling among you, my brothers. (1 Corinthians 1.10-11)
The call to be unified is clear. But, to what extent are we to be unified? We are divided by many things that we do not do exactly alike. For example, we are not unified in location (what a large house that would have to be!). Many have different occupations, and even more varying thoughts about their occupations. We eat different foods and enjoy various hobbies. So, in what things are we to be of the “same mind”? I believe the answer is written to the Ephesians.
Eager to maintain the unity of the Spirit in the bond of peace. There is one body and one Spirit—just as you were called to the one hope that belongs to your call— one Lord, one faith, one baptism, one God and Father of all, who is over all and through all and in all. (Ephesians 4.3-6)
Of these seven things there can be no variation. Offering hope in any variance of these things is no salvation at all! Imagine teaching salvation in Allah, baptism by anointing of oil, or an eternity living in Nirvana. Those principles are false and corrupt the message of Holy Scripture.
There is implication in scripture that we will have differing opinions at times. An easy example is to consider that what is modest has changed drastically over the years. (1 Timothy 2.9) At one time no woman would ever wear pants or show her ankle, nor a man who wear short pants in polite company.
Consider is Romans 14.2-3: “One person believes he may eat anything, while the weak person eats only vegetables. Let not the one who eats despise the one who abstains, and let not the one who abstains pass judgment on the one who eats, for God has welcomed him.” This matter is a difference in understanding of doctrine.
The next verse draws the line at passing judgement based on our understanding. We must be careful to let God judge gray matters and growth. Be understanding of opinions and welcome growth!
