As the procession entered Mass this morning we sang the Introit Laetetur cor - Let the heart of those who seek the Lord rejoice. Seek the Lord and be strengthened. Seek his face always. These words are taken from Psalm 104 (in our Greek numbering. St. Benedict has us sing it each week at Saturday Vigils). The idea of seeking God occurs several times in the Psalms (cf. e.g. Ps 39/40:16; 68/69:6 etc.) Another familiar Introit has a closely related text, taken from another Psalm (26/27:8-9): Tibi dixit cor meum - To you my heart has said, I have sought your face. I will earnestly seek your face O Lord. Do not turn your face away from me.
