Pope Francis wants every family to be a beacon of the joy of [God’s] love in our world.
Working towards achieving that will be a huge contribution to evangelising our diocese. Each of us can find a way to contribute to creating those beacons. Not just in how we each live our own family lives as Catholics but also supporting others as they try to live out their family lives.
Within our diocese our Director of Marriage and family life works with parishes and external organisations to promote and support marriage and family life as a key part of the mission of our church. https://www.dioceseofbrentwood.net/departments/marriage-family-life/ Fr Mathew can help you find opportunities for you to get involved.
External organisations like Catholic Marriage Care can offer volunteering and training opportunities as well.
