Today was the seventh Sunday of Ordinary Time.  The Scriptures for this week were about holiness.  Leviticus 19:1 was a call to holiness for the Jews in exile in Babylon.  In 1 Corinthians 3, Paul condemned factionalism by reminding the people that they are temples of the Holy Spirit and that all are in Christ rather than part of the flock of whomever converted them.  In Matthew 5, our Lord commands that we love our enemies, since even tax collectors love their own kin.  Our love must be perfect, as the Father's love is perfect.  That is holiness.
