Q: Why does the worship in the Anglican tradition usually have three to four scripture readings?

A: Proclaiming God’s word in worship began at the time of the Old Testament. In the past 2,000 years, the number of readings in worship varied. Most Anglican churches today include the Old Testament, the Psalm, the New Testament and the Gospel lessons in each service because the Church believes that every part of the Bible is important. Our reading arrangement, Lectionary, is based on a three year cycle. In three years, we will cover most parts of the Bible to allow Christians to obtain a comprehensive learning of God’s revelation in the scriptures.
