Nov. 23 Monday of the Thirty-Fourth Week of Ordinary Time; Optional Memorials of St. Clement I, pope & martyr; St. Columban, abbot; Bl. Miguel Pro, priest and martyr, Opt. Mem.

St. Clement is the third successor of St. Peter who ruled the Church from c. 92 to 102 and is mentioned in the Canon of the Mass. Pope St. Clement wrote a letter to the Corinthians, which is one of the most ancient and precious documents surviving from early Christian times; it shows his profoundly religious spirit, wholly imbued with the mystery of the things of God and love of Christian unity.
