"I will sing of your love and justice; to you, LORD, I will sing praise." (Psalm 101:1)
Psalm 101 is a royal psalm, a declaration by the king of the principles by which he will govern himself and his court. It is the oldest statement of leadership ethics in any religious literature. The king commits to a life of integrity in his own household: he will walk with a blameless heart, refuse to set anything worthless before his eyes, hate the deeds of those who fall away. He will silence slander, avoid the proud and arrogant, and surround himself with those who are faithful and walk in the way that is blameless. Every morning he will put to silence the wicked of the land.
The Catechism draws from the royal psalms a picture of the ideal ruler, whose authority is exercised in service of justice rather than self-interest (CCC 1897). But the Church Fathers also read this psalm as the description of every baptised person who is called to be a royal priesthood: each Christian is a king over their own interior household, responsible for what they allow in, what they refuse, and what principles govern the daily choices of their life. The morning resolution of verse 8 is the pattern of the Examen: each day begins with a renewed commitment to drive out what is inconsistent with the life of grace.
Brothers and sisters, what principles govern your household? Not the household of walls and roof but the household of your interior life: what you allow your eyes to rest on, what you permit your imagination to entertain, what company you keep in your heart. Psalm 101 is a royal charter for the interior life. Adopt it.
Lord God, I will sing of your love and justice and walk in my house with a blameless heart. Guard my eyes from worthless things, purge slander from my lips, and let your presence be the standard by which everything in my life is measured. Through Christ our Lord. Amen.
