Biblical Truths vs. Ecumenical Unity

“And Jehu the son of Hanani the seer went out to meet him to his face and said to King Jehoshaphat, ‘Should you help the wicked and love those who hate Yahweh and so bring wrath on yourself from Yahweh?’” (2 Chronicles 19:2, LSB)

Working well with others is something we were hopefully taught as small children. Learning to get along with people, even people we don’t often agree with, is a mark of maturity and a necessity in any healthy society.

But when discussing religion, particularly Christianity, do the same ideas of cooperation and friendly interfaith dialogues need to be pursued? If you are ecumenical, you’d probably answer in the affirmative, pointing out that Jesus was a peacemaker and taught His disciples to love all people.

Those, such as myself, who don’t agree with the central ideas of ecumenism would agree that Jesus came to bring peace and that we are to love all people. We should treat all people with care and respect, not just those who believe what we believe or look like we do.

However, Christianity makes truth claims, and those propositional truths often come into direct conflict with the ideas and philosophies of the world and those of all other religions and traditions. Ecumenism seeks to flatten out beliefs in favor of the lowest common denominator so that we can work together in harmony. For instance, Judaism, Islam, and Christianity come from an Abrahamic root. All three religions are also monotheistic. But if you poke just below these surface truths, you will find a lot of disagreement. Enough that wars continue to rage because of these critical underlying differences.

I find it no small matter that God Himself doesn’t embrace this ecumenical spirit that some claim in His name. In the Old Testament, false idols and their altars are repeatedly torn down, and their prophets are put to death. In the New Testament, warnings against idolatry continue (1 John 5:21; Colossians 3:5; 1 Thessalonians 1:9), with the result that external idols of wood and stone were still rejected, along with the internal idols of the heart.

In the above passage of 2 Chronicles 19, God rebukes the relatively godly king of Judah for working with the famously wicked king of Israel, Ahab. Ahab and Jehoshaphat partnered to fight a common enemy, which resulted in Ahab’s death in battle (2 Chronicles 18). And even though King Jehoshaphat forced King Ahab to seek out the Lord’s will before going to battle, as we see in the verse above, God was not pleased.

Hanani, the Lord’s prophet (called a “seer” in those days), went out for a face-to-face meeting with the king. God was angry, even though Jehoshaphat had maintained his godly reign, unlike so many other kings. Why? Because in partnering with Ahab to help him defeat an enemy, he showed love to one who hated Yahweh.

Some people justify their cooperation in ecumenical programs and fellowships because they say they will be able to maintain their biblical fidelity. Some even believe that they will be able to influence the ungodly and apostate by showing them what steadfast biblical faithfulness looks like. But let’s be honest, healthiness doesn’t spread like disease. It works the other way around. God knows that. That’s why He forbade the intermingling of the diseased with the healthy in His laws. That’s why it was such a big deal for Jesus to touch the sick and the dead. A rotten apple spoils the whole barrel. It never works the other way.

My biggest concern is not simply whether it works or doesn’t. Our biggest concern as Christians should be what God thinks about it. As we see throughout the Bible, and clearly in His response to Jehoshaphat, we risk bringing the wrath of God for the wicked upon ourselves when we love those who hate Him.
