Rabbi Aaron Chorin of Arad was an early proponent of religious modification; from the publication of his 1803 book "Emeq ha-Shave" and onwards, he dismissed Practical Kabbalah and the Zohar, authored guidelines for modernizing Judaism according to Talmudic principles and sought to remove what he regarded as superstitious or primitive elements, like spitting in the prayer of Aleinu.
[1] With the commencement of the Hungarian Reform Era in 1825, especially after virtually all limitations on Jewish settlement were removed in 1840, the Kingdom's Jews underwent rapid urbanization and acculturation, and many began to assimilate.
In addition, the local Liberals – Lajos Kossuth among them – insisted that Emancipation would be granted only after Jews abandoned the customs that set them apart from society so that they could fully integrate.
As in Germany, both moderate and extreme religious reformers in Hungary opposed this demand, claiming civil rights should be unconditional and that the changes they instituted were made for their own sake.
This style was carefully crafted by Isaac Noah Mannheimer to introduce aesthetic change without breaching the Shulchan Aruch; the bimah was set in the front of the hall, as in churches, and the wedding canopy was held inside rather than under the sky.
The Viennese Rite, wrote Michael Silber, was the key factor in what would be known as "Neology" in Hungary[1] – the designation itself was late, and was first used by the local Orthodox by the end of the 1860s, during the Congress controversy.
In 1845, the Ksav Sofer could still recommend that Jacob Ettlinger approach Löw Schawbb – Rabbi of the largest Neolog center, Pesth, and Leopold's father-in-law – and request to add his signature to a petition against the conferences assembled by Geiger and his colleagues.
Graduates of the Jewish Theological Seminary of Breslau, hub of Frankel's Positive-Historical School, were sought after by the liberal congregations in Hungary for the rabbi's office.
[5] During the 1848 Revolution, Ede Horn, a disciple of the radical German rabbi Samuel Holdheim, headed the Pesth Reform Association, where he abolished circumcision and moved the Sabbath to Sunday.
Löw and Schwabb condemned him sharply, and demanded the authorities close down the Association – now headed by David Einhorn, who arrived to replace Horn after the latter fled the country – and similar groups that sprung up at the time of the revolution.
Eventually, a committee chaired by Löw drafted a general constitution, which mandated the forming of a seminary as the only certified institute for training rabbis, sought to apply the aesthetic modifications practiced in Pesth across the country and aimed at creating schools for public education at the communities.
Jacob Katz viewed the constitution as an important testimony to the "emerging Neolog tendency": while it opposed any changes in the laws of religion pertaining to Sabbath and the holidays, marriage and divorce, dietary regulations etc., it also refused to apply any coercion to enforce them, whether by legal or social means.
The Modern Orthodox founder Azriel Hildesheimer arrived from Prussia to serve as rabbi of Eisenstadt, bringing with him the philosophy of Torah im Derech Eretz.
While the Neologs did not perceive the "Old Orthodoxy" of Moses Sofer's disciples as a potent competitor for the loyalty of the educated Jews, Hildesheimer signaled a different approach.
Neolog publications, especially Löw's Ben Chananja, launched constant tirades against the "Pest of Neo-Orthodoxy", castigating the Eisenstadt rabbi for merely presenting a shallow facade of modernity.
The Neologs and Hildesheimer often came to public dispute, with the most important taking place in 1863, after Heinrich Graetz was sued for dismissing the traditional concept of a personal Messiah.
Hildesheimer, who was bothered that public opinion did not perceive a difference between both groups in regards to observance, used the Graetz controversy to prove the existence of a dogmatic chasm.
However, no separation of Church and State took place, and all Hungarians were mandated to belong to religious bodies that collected their own taxes and retained control over aspects of civilian lives, like birth registrations and marriage.
"[11] The 1911 Central Conference of American Rabbis' Year Book noted with disappointment: "in the Szegedin and Budapest reform temples, there are no mixed choirs, no family pews, no bareheaded praying and not even confirmation of boys and girls.
[14] Another attempt for more radical innovations was made by the Pesth layman Ernő Naményi, who founded the Isaiah Religious Association (Ézsaiás Vallásos Társaság) in the early 1930s.
While congregations introduced synagogue organs, played by a non-Jew on the Sabbath, and mixed choirs, traditional liturgy was upheld; only few communities abolished Kol Nidre or Av HaRachamim.
Schweitzer concluded that while the Neolog rabbis were extremely moderate in their approach, they had little influence over the congregants of the Bureau communities, who were inclined toward full assimilation and religiously lax, at best.
[17] Prominent rabbinical authorities among the Neologs included also Immanuel Löw of Szeged, Leopold's son, who was one of only two rabbis to be given permanent seat in the Hungarian Upper House of Parliament, alongside the Orthodox Koppel Reich.
[18] The campaigns for granting Judaism the status of an "accepted faith", legally recognized and subsidized by government funds, for installing chief rabbis as members of the Upper House of Parliament and against Antisemitism – in the 1890s, 1920s and 1930s, respectively – were led by the Congressionals.
[19][20] In Yugoslavia, the 70 Neolog communities constituted the majority of the Federation of Jewish Religious Congregations (Savez jevrejskih veroispovednih opština) founded in 1919, together with 38 Sephardi ones; the 12 Orthodox refused to join and formed a union of their own.
