What ADSS shows is the intervention of Cardinal Serédi, in the Upper House of the Parliament attempting to if not prevent passage of the new bill then at least seeking to ameliorate those parts deemed contrary to the Catholic theology of marriage.
Act XV of the Hungarian Parliament in 1941, popularly known as the "Third Anti-Jewish Law" ended a process that had begun in 1938. The law of 29.05.1938 began the removal of Jews from the professions and Hungarian economic life. There were some exceptions, but the tone of future race-based legislation had been set.
Act IV of 1939 promulgated on 05.05.1939 defined Jews on racial grounds following the example of the Nuremberg Laws. Exclusion of Jews from the economic life of Hungary was accelerated. A Hungarian form of "aryanisation" in the figure of the Strohmann (Straw Man) ensured that while Jews were forced out of management and public ownership, Jewish business expertise was not lost. It was a cynical ploy, endorsed by the government, but allowed some measure of financial security for Jewish businesses. At the same time an estimated 90,000 Hungarian Jews were unemployed, and by government decree, unemployable. When the dependents of the 90,000 are added, the total number of Jews displaced by the new laws reached about 220,000 of a total population estimated at around 400,000. This number was to grow rapidly to over 846,000 between 1939 - 1941 when Hungary was given tracts of territory from Slovakia, Romania and the defeated Yugoslavia.
The final law was debated in the Hungarian Parliament in July 1941. This summary comes from the Hungarian website Social Conflict.
Act XV of 1941 (the third Anti-Jewish Law) on “The amendment and modification of marriage law XXXI of 1894, and the related necessary racial provisions” went into effect on August 8, 1941. Using Nazi terminology in its preamble, the law applied Germany’s Nuremberg laws: everyone with at least two grandparents born into the Israelite faith was defined as a Jew. The law also forbade marriage, and legally sanctioned extramarital sexual intercourse between Jews and non-Jews, provided the male was defined a Jew and the female was not. While the first two anti-Jewish pieces of legislation were accepted by Upper Chamber members representing Christian churches (Jusztinián Serédi, Catholic cardinal-primate, Sándor Raffay, Lutheran and László Ravasz Protestant bishops, as well as other church dignitaries), they strongly opposed the third law, as it drastically interfered with the marital status of converted Jews, thereby violating ecclesiastic jurisdiction.
