Note on godparents: According to Canon Law, sponsors or godparents must "be a Catholic who has been confirmed and has already received the most holy sacrament of the Eucharist and who leads a life of faith in keeping with the function to be taken on;" and that a "baptized person who belongs to a non-Catholic ecclesial community is not to participate except together with a Catholic sponsor and then only as a witness of the baptism." (Can.874 §1.3; §2)
Please ensure that at least one of the principal sponsors/godparents is a Catholic in accordance with the Church law quoted above (Can.874 §1.3) . Additional godparents act as witnesses to the baptism (Can.874 §2).
