and 15; R. Leib Baron, supra, note 68. R. Ben Zion Rosenthal maintains that bal tosif also applies to mitsvot which are optional (kiyyumiyyot); see R. Ben Zion Rosenthal, “Bal Tosif beMitsvah sheEina Hiyyuvit,” HaPardes 33:2 (Heshvan 5719), p. 17; R. Ben Zion Rosenthal, “Bal Tosif beVirkhat Kohanim,” HaPardes 33:11 (Av 5719), p. 16—reprinted in R. Ben Zion Rosenthal, Tenuvat Tsiyyon, secs. 42 and 43. Cf. Birkei Yosef, O.H. sec. 17, no. 2, who leaves the issue of bal tosif by women unresolved.
Finally, there is also some discussion as to whether there is a prohibition of bal tosif on one who adds to a rabbinic enactment. The consensus is that there is not; see Resp. Ketav Sofer, sec. 120; Sefer haMikna, kelal 51; Resp. Mishne Halakhot, Mahadura Tinyana II, H.M. sec. 478.
96.Those halakhic authorities who disagree with this ruling argue that a woman who voluntarily prays impliedly accepts all the requirements imposed upon one who is obligated to pray, i.e., a man; see note 97, infra. (For a discussion of the related view of Behag, see Resp. Benei Vanim, II, sec. 19, p. 72.) This contention has no logical parallel to women’s prayer groups. The latter clearly have no intention to constitute a minyan and could not halakhically constitute a minyan for public prayer even if they so intended. The voluntary assumption of obligation is not the same as legally imposed obligation; see Gidon Rothstein, “The Roth Responsum on the Ordination of Women,” Tradition 24:1 (Fall 1988), pp. 104-115; Sha’arei Tohar, I, supra, note 23. Minyan requires legally imposed obligation; see Aryeh A. Frimer, supra, note 3. An analogous argument can be found in R. Isaiah di Trani (The Elder), Piskei Rid, Rosh haShana 33a and again in Sefer haMakhria, sec. 78.
