It is a great dream to think of Church divisions being a thing of the past. There are so many different ways of worship, it can be difficult to accept the practice of someone whose belief is different from your own. Paul had a similar struggle in his day (several, in fact) and one of those were between Jews and non-Jews. Were Jews special? Were non-Jews part of a new plan from which Jews were now excluded? But Jesus came to resolve that tension, to close that gap. In him, we are one people, though we certainly need to work harder to live together.
