I’ll give you the other two paragraphs of the introduction as well:
After the priest invites us into this act, there is a brief pause for silent reflection and examination. Make proper use of this silence by calling to mind your sins – the ways you have failed to live out the Gospel in your daily life – and repenting of them. There has been a loss of the sense of sin in our world, with dangerous effects: so long as we’re healthy, wealthy, and wise (in the eyes of the world) we think we’re “all right.” On the contrary, Fr. Thomas Kocik wrote in Loving and Living the Mass that Jesus might say in our contemporary language, “it is better to enter heaven with a guilt complex than to enter Gehenna brimming with self-confidence.” (p. 43)
So how is this anything similar to the wild-but-tender side of Christ that we see in Matthew 21:12-14? “Do you not know that your body is a temple of the Holy Spirit within you?” (1 Cor. 6:19) “We are the temple of the living God.” (2 Cor. 6:16) We are temples, but we are marred by the stain of sin, as guilty as the money-changers though our sins might be completely different. We are temples, but we are plagued with sickness, as in need of Christ’s healing touch as were the blind and the lame. In the Penitential Act, Jesus Christ comes to us to cleanse us and to heal us of our sins.
