Thomas L. Kinkead, Baltimore Catechism, No. 4
“ To repeat what has already been said, godparents contract a spiritual relationship with their godchild, and in the event of marriage, they must make known this relationship to the priest. The godfather and the godmother do not contract a relationship between themselves, or with the child's parents, but only with the child so that neither the godfather nor the godmother could later marry their godchild without first obtaining proper dispensation; that is, permission from the Church granted by the bishop or Pope. ”
