Are we the bride of Christ?

[Aquila]

Remember, in ancient times betrothal was just as binding as the wedding. A man's betrothed was often called a "wife". Also, to terminate a betrothal a writ of divorcement was necessary. Scripture plainly says that Mary was Joseph's wife (Matthew 1:20,24, Luke 2:5). But at the same time, she was betrothed to him:

Matthew 1:18-19, "...Mary was betrothed to Joseph...Joseph...was minded to put her away."

So yes, although the marriage hasn't taken place yet, we are the bride of Christ.
