John Chrysostom

Those things which happened to Ruth should be seen as figures. For she was an outsider and had fallen into extreme penury; but Boaz, seeing her, did not despise her on account of her poverty, nor was he horrified on account of her impiety; even as Christ received the church, who was both a stranger and laboring, in need of great good things. Ruth is not joined with her consort before forsaking her parents and her nation and her native land: never was anyone so much ennobled by marriage. Thus the church was not made loveable to her spouse before she had forsaken her prior customs. The prophet says, “Forget your people.”
