Marriage De-idolized

From a piece by Tim Keller, Three Ways with Families, where he quotes from Stanley Hauerwas' book, A Community of Character (emphasis his):

The Christian gospel and hope of the kingdom-future de-idolized marriage. "Singleness was legitimated, not because sex was questionable, but because the mission of the church is 'between the times' [the overlap of the ages]…We must remember that the 'sacrifice' made by singles was not [just in] 'giving up sex' but in giving up heirs. There could be no more radical act than that! This was a clear expression that one's future is not guaranteed by the family but by the [kingdom of God and the] church…" ( Hauerwas, p.190). "[Now, in the overlap of the ages], both singleness and marriage are necessary symbolic institutions for the constitution of the church’s life... that witnesses to God’s kingdom. Neither can be valid without the other. If singleness is a symbol of the church's confidence in God's power to effect lives for the growth of the church, marriage and procreation is the symbol of the church's understanding that the struggle will be long and arduous. For Christians do not place their hope in their children, but rather their children are a sign of their hope . . . that God has not abandoned this world." (Hauerwas, p.191)
