Responsorial Psalm: Psalm 109(110):1-4

You are a priest for ever, a priest like Melchizedek of old.

The Lord’s revelation to my Master:
  ‘Sit on my right:
  your foes I will put beneath your feet.’

You are a priest for ever, a priest like Melchizedek of old.

The Lord will wield from Zion
  your sceptre of power:
  rule in the midst of all your foes.

You are a priest for ever, a priest like Melchizedek of old.

A prince from the day of your birth
  on the holy mountains;
  from the womb before the dawn I begot you.

You are a priest for ever, a priest like Melchizedek of old.

The Lord has sworn an oath he will not change.
  ‘You are a priest for ever,
  a priest like Melchizedek of old.’

You are a priest for ever, a priest like Melchizedek of old.
