Thou Price of My Salvation
The snares of the enemy have involved me in darkness: enlighten me, O Christ, who, when hanging on the cross, didst obscure the sun, and bring to thy faithful the rays of pardon. May I walk in the light of thy commandments and, being purified, come to the brightness of thy saving Resurrection.
The Liturgical Year by Dom Prosper Guéranger O.S.B. Volume 5 Lent, page 177
