Lay people are called to preach the Gospel in the world. As lay people, we have close contact with the world through our work and families. We preach the Gospel through our actions and also through meeting with people one on one and sharing our faith with them.
Bishops, priests and deacons preach the Gospel at Mass by giving homilies and sermons, and they can also preach the Gospel in the world just as lay people do.
Lay people can also set up lay apostolates such as the Legion of Mary, for going door to door inviting people to come to Mass and praying with them, and also we can get involved with the secular media such as television, radio, Internet, and newspapers, to promote the Gospel through these media.
