The readings for the 26th Sunday in Ordinary Time make a simple point: The Holy Spirit unites us to God and one another, while material attachments separate us.
In the first reading, Moses, following the advice of his father-in-law Jethro, invoked God's special blessing on 72 chosen men to help him in ministry. Even though two of the men weren't in camp at the time of the anointing, the Holy Spirit still fell upon them because they had been chosen.
The three readings for the 25th Sunday in Ordinary Time point out that when God enters into our lives, we lose our way. The things we had depended upon to carry out our life's project are undermined. We become confused and uncertain as to what's happening next.
The skills we have honed lose their purpose. Our life's goal falls apart; we're angry. What should have worked no longer does. What in the past gave consolation now leaves us hollow and empty.
The readings for the 24th Sunday in Ordinary Time are all about the power of the cross, alive in our midst. They refer to the passion of Christ as well as to the passion of every follower of Christ. Life is so much easier when we discover that Christ is alive in our passion, filling us with energy and hope.
The first reading, a servant song from Isaiah, is a hint of Christ's passion. It portrays God's servant as obedient in the face of trials. In the midst of intense suffering, he is very much aware that God is his helper every step of the way. The Lord God is with him to strengthen him.
