I'm not clear on how you got a "super-spiritual" impression from this article. For instance, it starts out with:
We must never exalt singleness (as some early church fathers did, notably Tertullian) as if it were a higher and holier vocation than marriage. We must reject the ascetic tradition which disparages sex as legalized lust, and marriage as legalized fornication. No, no. Sex is the good gift of a good Creator, and marriage is his own institution.
If marriage is good, singleness is also good. It's an example of the balance of Scripture that, although Genesis 2:18 indicates that it is good to marry, 1 Corinthians 7:1 (in answer to a question posed by the Corinthians) says that "it is good for a man not to marry." So both the married and the single states are "good"; neither is in itself better or worse than the other.
And goes from there. That sounds pretty down-to-earth to me.
BTW, threadgoers, I mistakenly linked to the second page of the interview. The beginning url is:
