This reflection on the Readings of the Holy Mass is perhaps one of the most offensive to the themes of the readings that I've ever run across.  They're not at all about the worn-out Marxist theories of the oppressed. 

The theme of the readings inarguably is about true, deep, costly charity for another, and which includes doing the will of God, including His Commandments, and as several of the readings point out, also includes notably the duty of Christian fraternal correction.

And interestingly, the Gospel passage provides a Scriptural basis for the Catholic social justice principle of subsidiarity.
