It sounded to me like this is something your aunt and your parents would most likely not do, probably because one or both religions actively teaches against something that is commonly taught in the other.
Actually the United Methodist Church practices open communion…so that is not true. I am fairly sure the Nazarene church does also.
However, this thread has strayed far from the original point so let me bring it back. What I was saying can be best illustrated by a hypothetical:
Let us say we start with religious organization ‘A’. This organization can be either a church…denomination…whatever.
On down the line let us say this religious organization splits into two organizations we will call A’ (A prime) and B. I use the A’ and B notation because it is quite a common occurrence that in a schism one of the parties keeps the property…retains the name…or whatever…while the second party vacates the property and adopts a new name.
Now imagine a fair minded, neutral observer who knows nothing about the details of the schism other than it happend. What would he conclude?
In the absence of any other data, the natural, default assumption would be that both A’ and B are descendents of A and both have equal claim upon A.
Now this is not the only logical possibility here. You have at least two others:
- Perhaps ‘B’ is a heretic organization and has no claims to A.
- Perhaps A had drifted from its original foundation and B is really A according to the founders of A.
(and you have all sorts of alternative explanations between these two extremes).
However, a fair minded, neutral observer would not start with either of these assumptions. He would start with the assumption that A’ and B are on equal footing with respect to A and would demand convincing evidence to reach another conclusion (burden of the proof being upon the one making the alternative claim).
Since I have not studied in detail how all of the branches of Methodism have come into existence, my natural assumption is that all branches have equal claim to the original A. I am applying similar reasoning in the case where A is now the apostolic church.
