One of the most impactful lessons I learned in seminary was regarding what my professor called orders of importance. His argument was that we have basically three levels of importance in the Christian life.
Firstly, we have things on which we must agree as the lowest common denominator for Christian faith. These have been called essentials or orthodoxy, but the bottom line is that we believe that a person must believe or affirm these things to be considered a Christian. In this category are things like the deity and humanity of Christ, justification by faith alone, and the necessity of repentance.
Secondly, we have things on which we must agree to have fellowship in one local body. In this category are things that are important, but that we believe can be disagreed on among brothers in Christ. However, disagreements on these things will make it difficult in the life of the Church. Mode of baptism is the first thing that pops into my mind. If we agree that baptism is not salvific (see paragraph one), we can disagree about the mode with other Christians. Members of one church, though, must agree about the mode of baptism so that we can conduct the ordinances of the church in unity. Other things that may fit into this category are church membership process, openness/closedness/closeness of the Lord’s table.
Lastly, we have things that we may disagree on that do not necessitate a break in fellowship. A brother and I may disagree about the end-times, but that does not mean that we cannot share a pew in the same church. Musical styles (depending on who you ask) are another thing that would fit into this category. These are things which believers in the same church may disagree on without any disunity in the local body.
Here’s the difficult part, we have a tendency to elevate everything into the first category. Everything seems to be vitally important as we deal with it. There are certainly some things that we must agree upon. The Scripture is clear on those things. We must stand firm on such issues. Other very important issues will affect the way we conduct business in the local body. We must come to agreement with our local body on these issues for the sake of unity.
My prayer is that the Lord will give us wisdom and clarity on deciding which issues belong in which category. The tried and true, “In essentials unity, in non-essentials liberty, in all things charity” is a great aspiration. May we humbly endeavor to disagree in a God-honoring way.
