When considering the CC’s stance on the validity of non-Catholic Christian marriages where both partners were validly baptized, it seems that they are deemed valid as long as neither were Catholic.
It is correct that a valid, licit Catholic baptism makes a person Catholic even if the person never receives confirmation or communion, right? So if they receive Catholic baptism as an infant, but as a teenager decide to be confirmed in another Christian tradition, they are still Catholic for purposes of defect of form marriage validity, right?
Under what circumstances does an emergency baptism or illicit but valid lay baptism according to the requirements of the CC inherently make a person “Catholic” (as opposed to just “Christian”), especially with regards to marriage requirements? If so, how does one tell the difference between a baptism that makes one Catholic and Christian versus a baptism that only makes a person Christian?
