Except in cases of emergency, the Church does not baptize children who will not actively be brought up in the faith:
Although the Church is truly aware of the efficacy of her faith operating in the Baptism of children, and aware of the validity of the sacrament that she confers on them, she recognizes limits to her practice, since, apart from cases of danger of death,
she does not admit a child to Baptism without its parents’ consent and a serious assurance that after Baptism it will be given a Catholic upbringing.* This is because she is concerned both for the natural rights of the parents and for the requirements of the development of faith in the child. (
Pastoralis Actio, n. 15)
- There is a long-standing tradition, appealed to by St. Thomas Aquinas (, IIa-IIae, q. 10, a. 12, in c.Summa Theologica) and Pope Benedict XIV (Instruction Postremo Mense of February 28, 1747, 4-5: DS 2552- 2553), against baptizing a child of unbelieving or Jewish parents, except in danger of death (1917 CIC, can. 750, par. 2) against the parents’ wishes, that is unless the parents ask for it and give guarantees.
The current Code of Canon Law (1983) has this to say on the matter:
Can. 868 §1 For an infant to be baptised lawfully it is required:
1° that
the parents, or at least one of them, or the person who lawfully holds their place,
give their consent;
2° that there be a
well-founded hope that the child will be brought up in the catholic religion. If such hope is truly lacking, the baptism is, in accordance with the provisions of particular law, to be deferred and the parents advised of the reason for this.
§2 An infant of catholic parents, indeed even of non-catholic parents,
may in danger of death be baptised even if the parents are opposed to it.
Note I’m not necessarily saying that unmarried people or those in marriages not blessed by the Church won’t bring their child up in the faith! I’m just making sure this part of the Church’s teaching is known.
