For ecumenism. The way all chrisitans are familys. Are because we all believe in God. Not all Chrisitan religions are exactly the same but we have many similiaraties. We're all united by Christ and we could hear out eachothers religions, and notice how similiar they are. Just like at the Vatican ll council there were many Christian religons who went to the Vatican ll council. Also we share similiar views with the other christians religions like on the views of Heaven and Hell, judgemennt and all those things. We are all still Christian brothers and sisters and all want peace.
