In this session we dealt with the gemara in Yevamot 24b that begins to raise the question of what are the healthy reasons to convert. The mishna describes the case of a woman converting for the sake of marriage. The gemara understands that this is less than ideal, however the conversion remains valid after the fact.
Subsequently, we began a theoretical discussion about the status and authority of decisions made by the beit din. Does a Jewish court have the ability to create physical reality in the world. For example, if the beit din says that a piece of meat is kosher and it is later discovered to have been not kosher – what is the status of the piece of meat.
The authority of the beit din is a flash point issue in the contemporary conversion controversy. Understanding the parameters of the retro-active annulment of a decision made by a beit din is not simple. (I will place a link to the source material when I return to my desk top computer.)
