The Meaning of Marriage

Wives, submit yourselves to your own husbands as you do to the Lord. Husbands, love your wives, just as Christ loved the church and give himself up for her to make her holy, cleansing her by the washing with water through the word, and to present her to himself as a radiant church, without stain or wrinkle or any other blemish, but holy and blameless" -Ephesians 5:22-28 [condensed]

The difference between a secular marriage and a Christ-honoring marriage is that in a Christ-honoring marriage your mission is to make each other better servants, to focus each other on your true vocations in life. The marriage is not between the bride and groom, but between God, the bride, and the groom. Hence why in most Christian ceremonies the minister asks the bride and groom a series of questions which they answer facing the minister and the altar (making their commitments to God). Then they recite their vows to one another either by repeating after the minister or by reading vows they have written down(making their commitments to each other). That entire first half of commitments is completely missing in a secular ceremony. Are secular marriages legitimate? Yes. Are religious marriages legitimate? Yes. But each serves an entirely different purpose. I've struggled with this, being a Christian who was dating a Jew up until a few weeks ago. I think it would be, well, impossible to have a Christ-honoring marriage with someone who does not believe in Christ (or was just raised with no real concept of Christ). Then I look at the  religions comparatively, and both believe in God (arguably the same God? God of Isaac) - I am wondering if a God-honoring marriage is the same as a Christ-honoring marriage. What do you think?
