Why do we hand on the faith?
We hand on the faith because Jesus commands us: “Go therefore and make disciples of all nations” (Mt 28:19).
No genuine Christian leaves the transmission of the faith exclusively to specialists (teachers, pastors, missionaries). We are Christ for others. This means that every genuine Christian would like God to come to other people, too. He says to himself, “’The Lord needs me! I have been baptised and confirmed and am responsible for helping the people around me to learn about God and to come to the knowledge of the truth’ (1 Tim 2:4b).”
Mother Teresa used a good comparison: “Often you can see power lines running alongside the street. Unless current is flowing through them, there is no light. The power line is you and I! The current is God! We have the power to allow the current to flow through us and to generate the light of the world: JESUS – or to refuse to be used and, thus, allow the darkness to spread.”
