CHOOSING A GODPARENT
29. Now the time has come to choose a godparent. What should the parent be looking for? When it comes to choosing a godparent, there are some who may strongly recommend relatives (including grandparents). Others may recommend a long-term friend. Both choices have their advantages and disadvantages. What is more important is to choose someone who:
29.1 can be trusted to maintain a long term relationship with the child;
29.2 is a practicing Catholic with a deep faith;
29.3 knows Catholic doctrines and understands the Sacrament of Baptism.
29.4 enjoys a prayer life;
29.5 is spiritual in his words and actions;
29.6 is prepared to guide the godchild towards salvation;
29.7 enjoys stability in his life;
29.8 has a high moral character;
29.9 enjoys patience and can relate to a child;
29.10 would be an exemplary model role.
30. While the choice of a good friend as a godparent is appropriate, sometimes friendships come to an end, leaving the godchild without an active godparent. Friends sometimes fade away after having moved to another city or out of the country. There is no guarantee that a friend will be able to maintain a twenty year commitment. While one may be properly disposed today, changes may occur tomorrow because of marriage, employment, health, etc...
31. Many parents choose family members as godparents, their decision being based on a sense of obligation. Some do it as an "exchange." "You be my child's godparent today and I will be your child's godparent tomorrow." Such a way of choosing a godparent frequently results in having a godparent who has little or no faith at all and who does not even belong to a Church.
32. Some people object to choosing a family member as a godparent because family members already enjoy a relationship with the child. They are concerned that the appointment of a relative may obscure their role as a godparent. Contrary to this belief, children who enjoy an aunt or uncle as godparent, they clearly distinguish their godparent from their other aunts and uncles.
33. Some parents, seeking gift-givers, choose godparents who are financially rich, but spiritually poor. Godparents should be spiritually rich, their financial status being unimportant.
34. In choosing a godparent, the parent should review the past of the candidates, their past being a reflection of what can be expected in the future. As a general rule, he who has not gone to Church for five years, he will not change overnight, nor persist in his faith.
I finally queued my girl up for the Sept's baptism.. she'd be nearing 8mth old by then! haha.
