Beyond the Rim... has a great explanation of why it's unfair to characterize the biblical position on marriage as saying celibacy is a higher calling, with marriage a fallback option.
There's a discussion of this also, with more focus on the passage from I Corinthians 7 that's often used to justify the view that celibacy is preferred, at Challies.com. I don't agree with either what Tim calls the traditional view or the one is he is presenting (but not necessarily endorsing) as an alternative, but it's an interesting discussion. If you want to know what I think, look in the comments. I do fully agree with everything he says in the followup post on whether Paul is reporting an uninspired opinion when he says "I, not the Lord".
