Roman Catholics believe that they have been commanded to participate in baptism as a demonstration and commitment to the Christian faith. They also believe that this baptism is essential to being saved from sin. Most Roman Catholics like to baptise their babies in the first few months after they are born, but adults also may be baptised. Baptism in the Roman Catholic church has several prerequisites.
Parents who wish to have their children baptised have to be registered members of the parish in which the baptism is going to take place. Generally, this means that the parents have to have attended the church and attended mass for at least two months.
If the person being baptised is under 7 years old, she doesn't have to take catechism classes (classes that teach what the Roman Catholic church believes). However, parents and godparents are required to take instruction, as are individuals being baptised who are more than 7 years old. If the parents and godparents already are practicing Catholics who have been baptised and who have had communion, then the instruction may be limited to baptismal responsibilities and beliefs only and is very brief (usually only a few hours). If the parents and godparents are not Catholic, they must take regular catechism courses over several months to become members of the Catholic church (not registered with the individual parish). This is because the parents and godparents act as sponsors for the person to be baptised and are expected to guide the baptised person in the Catholic tradition and faith. You usually don't have to attend this instruction if you've done it recently (within the past three years). If you wish a non-Catholic who hasn't received instruction to stand up with you at a baptism, you may, but they'll be witnesses only. At least one godparent must be Catholic.
Those who wish to sponsor a baptism must request baptismal forms from the parish office. These forms verify that the sponsor has met the requirements for acting as a sponsor, which (in addition to the instruction requirements) are as follows:
1) at least 16 years old 2) practicing Catholic with good standing in the church 3) not of the same gender as the second godparent 4) have received the sacraments of baptism, Eucharist and confirmation
If the requirements for certificates are met, the certificates then should be presented to the baptism coordinator for the parish.
