R. Gedalia Dov Schwartz recently reached the milestone of serving as the Av Beth Din of Chicago for 20 years. The Chicago Rabbinical Council published a book in honor of this event titled Sha’arei Gedula (link, scroll down). The book has a long biography of R. Schwartz, with plenty of "color commentary" added. The next and largest section is an overview of the halakhic challenges facing the American Orthodox rabbinate in the late nineteenth and early twentieth centuries. This is an extremely fascinating series of essays that, while lacking some of the historical sense of a trained historian, is nevertheless an extremely valuable historical treatment and simply a fascinating halakhic study. The final section is a long list of "Ask the Rav" questions and answers, often based simply on quoting other halakhic authorities but occasionally answered with R. Schwartz’s unique perspective.
Let me quote part of the section on conversion that is relevant to contemporary discussion. However, let me briefly note that this should not be understood as an endorsement of the work of the EJF because 1) it does not address their practice of reaching out to intermarried couples (link), and 2) it certainly does not justify their dismissal of the Modern Orthodox rabbinate (I, II).

Naturally, while there are teshuvos regarding the practical application of conversion, the teshuvos germane to intermarriage were principal in the minds of the twentieth century Rabbonim. For example, in 1927 Rabbi Chaim Fischel Epstein wrote concerning a woman who had converted in order to marry a Jew. The question was asked to Rabbi Epstein by Rabbi Yekusiel Yehuda Greenwald, was whether one would be permitted to perform the marriage of this couple in light of the halacha that a convert is not accepted unless his or her sincerity is substantiated, which would naturally preclude conversion for marriage. Rabbi Epstein wrote that the suspicion of insincerity only applies before the conversion; once the conversion is performed the principle of "???? ???? ?? – they are all converts" [see Yevamos 24b], takes effect. In addition, Rabbi Shlomo Kluger wrote that a conversion may be performed if there is a concern that the Jewish partner may otherwise become less religious. Accordingly, Rabbi Epstein permitted Rabbi Greenwald to perform the marriage [Teshuvah Shelemah, vol. 2 Even Ha-Ezer no. 10; see below].
