Answer:
   
   Reform Judaism and the Central Conference of American Rabbis has
   repeatedly opposed mixed (interfaith) marriages. However, it does not
   feel that once the marriage has occurred, the couple should be
   shunned, for this serves only to drive them further away from Judaism.
   This is best illustrated by a [5]resolution
   ([6]http://www.ccarnet.org/cgi-bin/resodisp.pl?file=mm&year=1973)
   issued in 1973 by the CCAR:
   
     The Central Conference of American Rabbis, recalling its stand
     adopted in 1909 that mixed marriage is contrary to the Jewish
     tradition and should be discouraged, now declared its opposition to
     participation by its members in any ceremony which solemnizes a
     mixed marriage.
     
     The Central Conference of American Rabbis recognizes that
     historically its members have held and continue to hold divergent
     interpretations of Jewish tradition.
     
     In order to keep open every channel to Judaism and K'lal Yisrael
     for those who have already entered into mixed marriage, the CCAR
     calls upon its members:
    1. to assist fully in educating children of such mixed marriage as
       Jews;
    2. to provide the opportunity for conversion of the non-Jewish
       spouse, and
    3. to encourage a creative and consistent cultivation of involvement
       in the Jewish community and the synagogue.
