The US Catholic Bishops have many resources available about the Third Revision of the Roman Missal, which was implemented on the First Sunday of Advent, 2011.
The US Conference of Catholic Bishops, in their document Stewardship: A Disciples' Response, wrote: "As Christian stewards, we receive God's gifts gratefully, cultivate them responsibly, share them lovingly in justice with others, and return them with increase to the Lord." A summary of the document is available.
