If you want to have a child baptised, speak to the Parish Priest who will explain what has to take place in terms of preparation for the sacrament, choosing Godparents, booking a date, choosing readings and prayers etc.
If you are an adult who has not been baptised and are thinking about becoming a Catholic, then there is a programme called the Rite of Christian Initiation for Adults or RCIA which is run in the parish usually starting in September each year. In the first instance, please come along and join us for Mass and meet us and, if you like what you see, speak to the Parish Priest to discuss your interest further.
