I know this is the traditional teaching, that it is forbidden to baptize the children of concubines -those who are not married yet are living together- but is this the rule in the Novus Ordo too, even though of course no one follows it?
I know that many things in the NO are still how they have always been -in paper- but everybody just ignores them, so I was wondering if this was one of them.
The 1917 Code of Canon Law did not stricly forbid the baptism of the children of those who were living in sin. Here it is from the Code of 1917;
Can 750 §1. Infans infidelium, etiam invitis parentibus, licite baptizatur, cuм in eo versatur vitae discrimine, ut prudenter praevideatur moriturus, antequam usum rationis attingat.
§2. Extra mortis periculum, dummodo catholicae eius educationi cautum sit, licite baptizatur:
1º Si parentes vel tutores, aut saltem unus eorum, consentiant;
2º Si parentes, idest pater, mater, avus, avia, vel tutores desint, aut ius in eum amiserint, vel illud exercere nullo pacto queant.
Can 751. Circa baptismum infantium duorum haereticorum aut schismaticorum, aut duorum catholicorum qui in apostasiam vel haeresim vel schisma prolapsi sint, generatim serventur normae in superiore canone constitutae.
A rough translation says
Canon 750 § 1. An infant can not be trusted, even against their parents, is licitly baptized when he is in a critical situation wherein, in order that it is prudently foreseen die, before the use of reason fails to attain to.
§ 2. Apart from the danger of death, so long as his Catholic education provision has been made, is licitly baptized:
1 º If the parents or guardians, or at least one of them must consent;
2 º If the parents, that is, father, mother, grandfather, grandmother, or guardians are not available, nor the right of him they have lost, or that they may be able to exercise in any way.
Canon 751. Concerning the baptism of the infants of the two of heretics or schismatics, or apostasy, or heresy, or schism of two fallen away Catholic who is in the they may be, in general, to observe the norms in the former the canon established as follows.
Apparently if the Catholic upbringing is provided for then the child can be licitly baptized.
