The 2nd Reading for this feast, Colossians 3:12-17 (or 12-21), includes the line
Let the word of Christ dwell in you richly (3:16)
Other translations render this as
Let the Word of Christ, in all its richness, find a home with you.
or similar words, and this is the genesis of today’s antiphon.
We can be thrilled by the double meaning of wanting the proclaimed words of God to make a home in us, and wanting the Word himself, the Logos, to make us his dwelling-place as we open ourselves to receive him in Communion. The repetition of the opening phrase will encourage us to ruminate on these mysteries.
The psalm verses are taken from Psalm 146, Psalm 127 (suggested in the Graduale Romanum) and Psalm 45, evoking a household that reflects God’s own house, and the many blessings that children can bring to a family.
