Christian stewardship involves lovingly sharing the gifts that God has given to us.
The bishops of the United States established the national collections to support the Church's works of social justice, evangelization and education, both domestically and around the globe. Jesus reminds us that the two greatest commandments are to love God with our whole heart, our whole mind, and our whole soul; and to love our neighbor as ourselves. The national collections offer us an opportunity to help our neighbors in the light of the Gospel. In doing so, we act as faithful stewards of the gifts God has given us.
