For parents who bring children to be baptized, the service involves making promises before God and the congregation to be a wholehearted disciple of Jesus Christ – and to show evidence of that commitment by being part of the church community. This is a tough commitment to make in the 21st century, and is something to be thought through seriously.
A baptism is also a celebration, often with lots of friends and relatives, but rather more is involved. The Parents and Godparents make very solemn promises before God which are effectively a public declaration of basic Christian belief involving:
(i)… deciding to turn away from the natural way of doing things, and letting God rule every area of our lives (what the Bible calls "repentance") and
(ii)… deciding to follow Jesus Christ and accept God’s forgiveness made possible by his death on the cross (this is what the Bible calls choosing to "believe").
The promises and statements you and Godparents make are to be seen in the link at the bottom of the page – they cannot be made lightly!
Similarly, we pray and trust that a baptized child will grow up to understand and appropriate for themselves the promises made in baptism. For this reason, it is important to understand that baptism is the beginning of a spiritual journey within the family of the church – not a one-off event which means that a child is "done"…
Because baptism is so tied in with being part of the church family, we normally have a baptism in the main morning service on a Sunday, so that everyone can join in welcoming your child.
