From the article; " .... struggle to live the Christian ideal of marriage and family life, the chief task of the church's theologians ... " 

I believe the use of the generic "Christian" to be telling. The "Catholic" ideal of marriage is somewhat different from the generic Christian ideal. The generic Christian ideal generally does not condemn nor ban divorce, remarriage, or birth control, and offers an unfettered path to their communion rail -- in short, full acceptance into the community. More and more of the generic Christian communities also recognize same-sex marriages.

The Catholic ideal of closeness ends prior to the Eucharist -- from that point on the Catholic leaves the divorced person to return to his/her spiritual loneliness. And because this is true, it is wrong to characterize this Catholic attempted closeness as "Christian".
