Why are converts included in the halachic category of zonah for purposes of the restrictions on whom a kohen may marry? Is the prohibition against a kohen marrying a convert biblical, or is it a rabbinic interpretation or enactment?
Furthermore, does the reality today require that this categorical prohibition be maintained, or is there room for reconsideration? In other words, does the classification of converts as zonot in the time of Chazal still make sense to maintain today?
If the inclusion of converts in the category of zonah is rabbinic, will a future Sanhedrin be able to reassess this rule and possibly permit marriages between converts and kohanim?
Thank you!
The Torah (Vayikra 21:7) prohibits a Kohen from marrying certain women, including a zonah and a divorced woman.
The halachic term zonah does not mean a prostitute. It has a specific legal definition, and the inclusion of a convert in that category is discussed extensively in the Gemara and Rishonim. Although the Biblical basis is less explicit than the prohibition concerning a divorced woman, many major Rishonim consider the prohibition against marrying a convert to be Torah law.
None of this means that a woman who converted is somehow inferior or has done anything wrong. A Kohen has special requirements of kedushah because of his priestly status. For example, he cannot marry a divorced woman either. What did she do wrong? Nothing. These are restrictions placed on the Kohen, not judgments about the women.
However, there is another very important consideration.
It is well known that many major Poskim questioned the certainty of the lineage of Kohanim in later generations. See Maharshdam, Even HaEzer 235, and Shvut Yaakov, Vol. 1, Siman 93. They discuss how uncertainty about whether someone is actually a Kohen can affect certain marriage restrictions.
Today, after so many generations of exile, displacement, and loss of genealogical records, this is an important issue to consider.
Therefore, if a Kohen is considering marrying a convert, I would encourage him to contact me privately with all the details. We would need to ask some questions about his family background and examine the particular circumstances to determine whether there is a legitimate halachic basis to permit the marriage.
This is not something that can be decided with a blanket ruling on a website. Each case needs to be evaluated individually.
