Welcome back to the Sunday Mass notes. This week we begin with a reading from the book of Acts. The full title for the book is The Acts of the Apostles, relating the beginnings of the church that Christ established. Today’s reading involves a portion of one of the Apostle Paul’s missionary journeys. By contrast, the second reading is from the next-to-the-last chapter of the Bible, Revelation 21, which gives us exciting information about the new heaven and earth that God will bring into existence. The final reading, from John’s Gospel, relates important words of Jesus on the night before His death, words that are intended to give us a means by which we can be known as His disciples.
