In their Pastoral Letter on Stewardship, a Disciple’s Response, the U.S. bishops state:
The Christian steward is one who receives God’s gifts gratefully, cherishes and tends them in a responsible and accountable manner, shares them in justice and love with others, and returns them with increase to the Lord.
Just a few examples of giving of your time, talents, and treasure…time spent praying, adoring, staying in contact with the homebound, volunteering at Mass, giving money to support your parish.
