The man was a church attending Catholic until getting married to a non-Catholic Christian woman. The wedding took place at the non-Catholic church and no permission was sought from the Catholic Church to do this (if there is such thing as a permission for this I don’t know). The man doesn’t attend mass anymore but has no interest in joining the non-Catholic Christian church attended by the woman. They have multiple children in between 10 and 3 years of age and the wife is sterilized. The wife is probably somewhat hostile to the Catholic faith, the man probably has some interest, at the very least sentimental interest.
What are the options for convalidation to get the man out of what I presume is mortal sin? Is there a promise to raise children Catholic? The wife would probably not allow this. What about when the kids are older? Would the wife have to agree to the convalidation?
