February 10th is the First Sunday in Lent. In the Gospel reading from St. Matthew's Gospel, we hear of our Lord's forty day fast and the subsequent temptation He was allowed to undergo after His fast. Three times, the devil tried to have our Lord veer from His appointed mission, and three times our Lord used Sacred Scripture to reply to the temptation. Sin which entered through the disobedience of Adam, as the readings from Genesis and Romans describe, is undone by the obedience of Christ.

Readings:

Genesis 2:7-9; 3:1-7
Psalm 51:3-6; 12-14,17
Romans 5:12-19
Matthew 4:1-11

Here are a few commentaries on these readings:
