In a 2001 article "Between Intermarriage and Conversion: Finding a Middle Way" published in CLAL, Greenberg proposes using the rabbinic concept of "ger toshav", (resident alien), to provide an accepted place for non-Jewish partners of intermarried couples, allowing them to experience "the joys of living in a Jewish home without insisting on conversion". As a marriage of a Jew and a ger toshav would not be legitimate under halachic law, Greenberg suggests using "cultural creativity" to find "new rituals that partake of Jewish resources and speak honestly about what is actually happening", the same as for gay couples, where in his opinion "kiddushin, the traditional ritual for the Jewish wedding, simply doesn't apply".
