Today, the mid-point of Lent, was celebrated with somewhat joyful spirit in ancient times. This day was a breathing space in the center of Lent's austerities. Today's ancient Entrance Antiphon and Opening Prayer express this encouraging spirit. Modern Lent is less austere, less in need of any breathing space. Today's lesson: be faithful to God, and do not ever fall away. It is a lesson to strengthen us for the remainder of Lent. --The Vatican II Weekday Missal
