May an Illegitimate Child Be Ordained?
Can an illegitimate child become a priest?
The 1917 Code of Canon Law (can. 984 n.1) did indeed state that men who were illegitimate children were "irregular" (i.e., would need a dispensation from Rome) for ordination. However, this code is no longer in force. The 1983 Code of Canon Law (can. 1041) does not list illegitimacy among the things that make a man "irregular" for ordination.
