Baptism involves making promises before God about the way one chooses to live, stating your belief in God (the Apostles Creed), then being ritually washed by sprinkling with or immersing in water which has been blessed, and having the sign of the cross made on you, sometimes with blessed oil.
If the person is too young to make these promises themselves, the parents will usually choose godparents who will make promises for and on behalf of the child. It’s worth knowing that a godparent needs to be physically present during the ceremony in order to make these promises.
The normal practice within the Anglican Church when a person has been baptised as a child is to be confirmed by the Bishop or Archbishop at a later time.
Baptism in the Anglican Church is normally accepted as suitable for membership in any of the mainstream or orthodox Christian traditions.
