21st Sunday in Ordinary Time (Year C) Aug. 21 (Isaiah 66:18-21; Psalm 117; Hebrews 12:5-7, 11-13; Luke 13:22-30)

The third section of the Book of Isaiah has a universal outlook that is both inspiring and moving. During their exile in Babylon, the people of Israel continued to reflect on their understanding of God and their new experience in an alien land. Their vision of God evolved — no longer was God merely Israel’s deity, but the God of all humanity.
