From St. Clement of Alexandrias' "The Stromata", Book VII, Chapter XI:
'They say, accordingly, that the blessed Peter, on seeing his wife led to death, rejoiced on account of her call and conveyance home, and called very encouragingly and comfortingly, addressing her by name, "Remember thou the Lord." Such was the marriage of the blessed and their perfect disposition towards those dearest to them.
Thus also the apostle says, "that he who marries should be as though he married not," and deem his marriage free of inordinate affection, and inseparable from love to the Lord; to which the true husband exhorted his wife to cling on her departure out of this life to the Lord.'
