February 14th : Responsorial Psalm

Psalm 50(51):3-6,12-14,17 

*Have mercy on us, O Lord, for we have sinned.*

Have mercy on me, God, in your kindness.
  In your compassion blot out my offence.
O wash me more and more from my guilt
  and cleanse me from my sin.

*Have mercy on us, O Lord, for we have sinned.*

My offences truly I know them;
  my sin is always before me
Against you, you alone, have I sinned;
  what is evil in your sight I have done.

*Have mercy on us, O Lord, for we have sinned.*

A pure heart create for me, O God,
  put a steadfast spirit within me.
Do not cast me away from your presence,
  nor deprive me of your holy spirit.

*Have mercy on us, O Lord, for we have sinned.*

Give me again the joy of your help;
  with a spirit of fervour sustain me,
O Lord, open my lips
  and my mouth shall declare your praise.

*Have mercy on us, O Lord, for we have sinned.*
