Blessed Virgin Mary on Saturday: "anyone begotten by God does not sin"

... but the one begotten by God he protects, and the Evil One cannot touch him.

-- 1 Jn 5:14-21

The Church is holy: the Most Holy God is her author; Christ, her bridegroom, gave himself up to make her holy; the Spirit of holiness gives her life. Since she still includes sinners, she is "the sinless one made up of sinners." Her holiness shines in the saints; in Mary she is already all-holy.

-- CCC 867
