Question: In many Ashkenazic communities, particularly in Chassidic circles, they do not daven with the traditional Nusach Ashkenaz. Instead, they daven a nusach known as nusach Sefard which incorporates some elements of Sephardic nusach into nusach Ashkenaz. What is the source of this nusach, and how did it become accepted despite the above teachings that a community may not deviate from its traditional nusach?

Discussion: The origins of nusach Sefard are based on the following idea: As mentioned above, there are twelve gates in Heaven corresponding to the twelve tribes. There is, however, a thirteenth gate designated for those who do not know their lineage. If a person davens using a nusach which is compatible with this thirteenth gate, his tefillah will enter through that gate regardless of his lineage. Arizal, with his Kabbalistic aptitude and Divine revelations, was able to cull various elements from the different nuscha’os to form a nusach which he deemed capable of entering through this thirteenth gate.119

The argument to change one’s nusach to nusach Sefard is that, based on Arizal’s teachings, a person davening with this nusach can be assured that his tefillos will be readily accepted in Heaven. This has become the accepted practice in all Chassidic communities.120

Question: If a person who davens nusach Ashkenaz lives in a Chassidic community where they daven nusach Sefard, may he change his nusach from Ashkenaz to Sefard, or vice versa?

Discussion: There are three approaches among the Poskim regarding this question:

1. Some allow a person to change his nusach from Sefard to Ashkenaz but not from Ashkenaz to Sefard. They explain that originally all Ashkenazic Jews davened nusach Ashkenaz. Although some of them changed to a new nusach, if they decide to change back to Ashkenaz, they are merely returning to their original heritage rather than changing their nusach.121 This would not be true for one who wishes to change from Ashkenaz to Sefard.122
2. Others allow one to change from Ashkenaz to Sefard but not from Sefard to Ashkenaz. Their argument is that since Sefard is the superior, all-inclusive nusach, one may change to that nusach to enhance his tefillah. Whereas a person whose tradition is to daven Sefard may not change to a nusach which might possibly not be compatible with his lineage.123
3. A third opinion maintains that one must stay true to his tradition and not change his nusach in either direction.124
