Culled from a religious feminist blog discussing the Barna survey:
All the women I know who are not in church are amazing followers of Christ who are tired of church yuckiness destroying their faith walk.
OK, right. Now let's try the same scenario in a related biblical context:
All the women I know who are not living with their husbands are amazing wives who are tired of husbandly yuckiness destroying their marriage.
Wait for it.
Nope. It just doesn't work, does it?
It didn't for St. Cyprian either, who wrote in De Unitate Eccslesiae:
"He can no longer have God for his Father who has not the Church for his mother; . . . he who gathereth elsewhere than in the Church scatters the Church of Christ" (vi.); "nor is there any other home to believers but the one Church" (ix.).
It wasn't just St. Cyprian who thought that. The maxim has been repeated down through the Church Age by Catholic and Reformed.
