That very day Herod and Pilate became friends. Previously, they had been hostile toward each other. – Luke 23:12
There is an old idiom that states, “Politics makes strange bedfellows.” It means that people who would normally dislike and avoid one another will work together if they think it is politically useful to do so (according to the Free Dictionary). This is usually true in politics, it was a key to the defeat of Hitler in WWII (see above), and it was certainly the case in the crucifixion of Jesus of Nazareth.
One man (the figurehead leader of an oppressed people), the other (a titular head of the local oppressor), Pilate and Herod became friends when confronted with the “problem” that was the Person of Jesus Christ. Neither one knew what to do with Him and neither one wanted to be responsible for His death. Though they abused and rejected Him, they were both afraid to kill Him. Their shared fear ultimately united them as “friends.”
If you follow Christ, you should not be surprised by the seemingly odd alliances resulting from a fear or dislike of Whom you follow. Just remember this, no matter the strength of the united enemy against the cause of Christ, His purpose and plan will not be defeated.
I give thanks unto my God for this; that I am found worthy to be among those whom the world hateth. – Jerome
