The “issue” about which a questioner bemoans that “there is no consensus” is marriage, divorce and remarriage. The problem with this way of thinking is that no doctrine of God is up for vote! Irrespective of whether mankind can muster a consensus of approval respecting any doctrine of God, divinely given, inspired truth is absolute and unchangeable. New Testament truth was decided upon and delivered to mankind nearly 2,000 years before any contemporary person was born. The decisions regarding biblical doctrine were made before any of us made our respective debut on planet earth, and God asked none of us for our opinions. Neither has Almighty God crowned any living person with the authority to countermand biblical Truth. Jesus Christ had and has “all authority… in heaven and on earth” (Matthew 28:18 NKJV), and He has not surrendered any of it to mere mortals – and certainly not to anyone living today.
New Testament teaching in a nutshell regarding marriage, divorce and remarriage is contained in primarily two passages – Matthew 19:9 and 1 Corinthians 7:10-11. Jesus Christ Himself uttered what we find in the first of those two references. The apostle Paul attributed what he penned in the latter citation to Jesus Christ as well. Jesus Christ alone is responsible for the teaching about marriage, divorce and remarriage that is applicable in the Christian Age, and it matters not all whether members of the church can come to a consensus among themselves about what to believe and practice.
