Is it Permissible to Renovate or Build a New Building During the Nine Days Which begin on Rosh Hodesh Av? Responsa in a Moment: Volume 10, Issue No. 8, July 2016

At the outset, I would like to stress the importance of the laws of Tisha B’av. On the one hand, I believe that it is very important to fast on Tisha B’av and to remember the Destruction in our day, even after the rebirth of the State of Israel and the reunification of Jerusalem. On the hand, there are many stringencies connected to “the three weeks” between the 17th of Tammuz and the 9th of Av, which were added in the Middle Ages by Aveilei Tziyon [= Mourners of Zion] and Ashkenazic rabbis, which have no Talmudic basis and which, in my opinion, there is no reason to observe.

What is the Proper Way to Refer to the Parents of a Convert? Responsa in a Moment: Volume 10, Issue No. 4, January 2016

I am officiating at the wedding of a young couple in the near future. In preparing the ketubah [marriage contract], I learned that the groom’s father was born Jewish, but the groom converted at age four, along with his mother. The groom would like his name to appear in the marriage contract as “X the son of the names of his two parents,” since they are all Jewish now; but his father would like it to appear as “X the son of Abraham and Sarah,” since that is how his son was named at his conversion. What is the halakhah in this case?

As a Driven Leaf by Rabbi Milton Steinberg – Notes and Sources Responsa in a Moment: Volume 9, Issue No. 7, July 2015

As a Driven Leaf by Rabbi Milton Steinberg is one of the most successful Jewish historical novels ever published in English and certainly the most successful novel related to the Talmudic period. It has been a best-seller since 1940. For the past five years I have been editing a Hebrew translation entitled K’aleh Nidaf, which was co-published in May by the Schechter Institute and Yediot Sefarim and is now on sale at all major book stores in Israel. The Hebrew version contains a forty-page Appendix in which I tried to provide all of the sources quoted or hinted at in the book and explain the historical background.

Is Judaism Really in Favor of Pluralism and Tolerance? Responsa in a Moment: Volume 9, Issue No. 6, June 2015

During the past two months, we have witnessed three major cases of a lack of pluralism and tolerance in the State of Israel, most of them carried out by Israeli Orthodox rabbis. They seem to believe that there is only one correct way to be Jewish and that those who deviate from that path are not real rabbis and should be shunned. Since these Orthodox rabbis from different backgrounds seem to share this lack of pluralism and tolerance, maybe they are simply reflecting the concensus of Jewish tradition. Is this true?

Why do we Decorate Synagogues and Homes with Trees and Flowers in Honor of Shavuot? Responsa in a Moment: Volume 9, Issue No. 5, May 2015

The first to mention this custom was the Maharil, Rabbi Yaakov Mollin (d. 1427), who is the source for many Ashkenazic customs:
It is customary to spread on the floor of the synagogue spices of grasses [i.e., sweet-smelling grasses] and shoshanim [i.e., lilies] to rejoice in the Pilgrim Festival. And when Shavuot falls on Sunday, Mahari Segal [the Maharil] instituted to spread the grasses on Friday (Minhagei Maharil, ed. Spitzer, p. 160).
