In chapter 12 Paul addresses the importance for those within the body to “love one another.” In chapter 13 he speaks to loving our neighbors. Now, in Chapter 14 Paul provides instruction on the relationship we should have within the Body when we may have differences of opinion on matters that are not scripturally based.
Romans 14: 19 Let us therefore make every effort to do what leads to peace and to mutual edification.
There are certainly times when we may disagree with a Brother or Sister. Our mission is to acknowledge the difference but to not disrupt the unity of the Body.
