For as a young man marries a young woman, so shall your builder marry you, and as the bridegroom rejoices over the bride, so shall your God rejoice over you. Isaiah 62:5
Most Christians are familiar with the imagery of “the church” as the bride of Jesus. It’s led to all sorts of infighting amongst the literalist factions about just what doctrines and dogma make which denomination or sect the most worthy “bride.”
Which is just another example of why all analogies have limits and why stretching those limits can make the metaphor incomprehensible.
The author of Isaiah was talking about the return of the Israelites from exile. No doubt that analogy may have seemed perfectly relevant to the founders of Christianity. But for us, living in a pluralistic world, it has long since ceased to convey the power of our inseverable relationship with Theos.
The strength of that relationship doesn’t lie in enforcing an artificial uniformity on our faith. It lies in recognizing the unity within our diversity, just as those were scattered throughout the Roman Empire recognized their unity no matter what their origins had been.
