Readings from Scripture are part of every Mass. At least two readings, one always from the Gospels, (3 on Sundays and solemnities) make up the Liturgy of the Word. In addition, a psalm or canticle is sung.
These readings are typically read from a Lectionary, not a Bible, though the Lectionary is taken from the Bible.
How can anyone own the copyright on the Bible? Isn't it free to everyone?
No one owns the copyright on the Bible itself. Rather, the copyright is held on particular translations or editions of the Bible. The Confraternity of Christian Doctrine (CCD) owns the copyright on the New American Bible translation. Some versions of the Bible, such as the King James Version (not the New King James Version) are in the public domain.
The copyright allows the owner to protect the integrity of the text so that individuals may not introduce changes without permission. Royalty fees earned by licensing the text to companies who publish and sell Bibles help to provide funds for Scripture scholarship and other educational needs.
How is the Lectionary arranged?
The Lectionary is arranged in two cycles, one for Sundays and one for weekdays
What's the difference between a Bible and a Lectionary?
Lectionary is composed of the readings and the responsorial psalmassigned for each Mass of the year (Sundays, weekdays, and special occasions). The readings are divided by the day or the theme (baptism, marriage, vocations, etc.) rather than according to the books of the Bible. Introductions and conclusions have been added to each reading. Not all of the Bible is included in the Lectionary. Individual readings in the Lectionary are called pericopes, from a Greek word meaning a "section" or "cutting." Because the Mass readings are only portions of a book or chapter, introductory phrases, called incipits, are often added to begin the Lectionary reading, for example, "In those days," "Jesus said to his disciples," etc.
