It is wonderful, and now they need to acknowledge Yeshua as Messiah and Lord. That’s my prayer for them and for all! (Orthodox Jews make some of the best believers.) Maranatha!
We don’t know what might be taking place in the hearts of these Rabbis. Jews all over the planet have been realizing that Jesus fulfilled all the ancient Hebrew prophecies regarding Messiah, and trusting Him as their Savior. If these Rabbis are new believers, or near believers, it’s very shrewd of them to couch their appeal for a truce and cooperation as they did, and not drop the whole conversion bomb on their people all at once.
I appreciate Christianity in that it brings people who would otherwise be pagans closer to the truth. But no, we don’t have to recognize anyone as the Messiah until he comes.
