This teaching is based on the Scripture passage, Circumcise therefore the foreskin of your heart, and be no longer stubborn (Deu 10:16). It explains what the circumcision of the heart is, its importance for our transformation, and how to live it.

By contrasting the example from the Old Testament where Moses is frustrated and angry with the Israelite people and the complaining of the Israelites with the manna (Numbers 11), and Jesus’ words in Mathew 11 on taking His yoke upon us and learning from Him, we understand how to live more intimately united with Jesus in His Eucharistic life.

This teaching explains the spiritual journey through the Cross to transformation in Christ.
