We believe and trust in one God, Father Son and Holy Spirit
At the heart of our faith is the belief in God as Father, Son and Holy Spirit. Christians believe that Jesus is God’s Son. Jesus reveals to us that God is our Father, and that God is available to us through the Holy Spirit.
You will never be asked if you completely understand all this, because it can be difficult to understand at times. But you are asked whether you believe and trust. This is called faith. It is a different sort of knowledge. It is the knowledge of being known and loved, and of loving in return.
The Christian faith is not a human invention. There are signs of God’s existence and handiwork in creation for anyone to read ( Acts 14.15–17 ). But we believe in the way we do because God has come to seek us out and has made himself known to us.
Archbishop Justin Welby explains
The most important decision any person can ever make is to become a disciple of Jesus Christ. It’s the best thing anyone can do.
When someone becomes a follower of Jesus they are baptized. (Or, if they have already been baptized, they will confirm for themselves the promises made at their baptism during the confirmation service). During this service a series of questions will be asked – in most respects the questions asked today are the same as those new Christians were asked in the earliest days of the Church.
Brothers and sisters, I ask you to profess together the faith of the Church.
Do you believe and trust in God the Father?
Do you believe and trust in his Son Jesus Christ?
Do you believe and trust in the Holy Spirit?
Everyone answers with either a simple “I believe and trust in him”, or by reciting the three parts of the Apostles' Creed , one of the most ancient summaries of the Christian faith.
Being a Christian means responding to Jesus’ invitation to enjoy a relationship with God here on earth and for eternity.
