Pomoću hebraistike, grecistike i poredbeno–povijesne metode u religiologiji, rad istražuje etiku ranih (judeo)kršćana i farizeja kao usko povezanih židovskih sljedaba u 1. stoljeću. Nakon što ističe razlike između farizejskih škola Ḥillēla i Šammâya te razmatra je li i Isus bio ḥāḵām, rad tumači razgovor o najvećoj zapovijedi u Mk 12 kao susret u dijalogu između farizeja Ḥillēlove škole i Isusa. Rad nastoji doprinesti međureligijskomu dijalogu i razumijevanju bitne povezanosti religije s etikom. The paper explores the ethics of the early (Jewish) Christians and Pharisees, two closely related Jewish sects at the beginning of the Common Era, through both Hebrew and classical philology as well as the comparative method within religious studies. It attempts to show that Jews and Christians can improve and complement their knowledge of their proper traditions and traditional values by means of a comparative study on the writings of the other’s tradition. The paper enumerates and explains five important distinctions between the Pharisaic Schools of Hillel and Shammai. Furthermore, it reconsiders the Hakamic movement as a peculiar phenomenon of the Second Temple period of which Hillel and Jesus, both teachers of wisdom and Jewish Law, were in fact representatives. It compares the formulations of the Golden Rule by Hillel, Jesus and the Didaché and argues that both Hillel and Jesus derived the Rule from their common oral tradition of Law. Its presence in the Oral Law is affirmed by Philo of Alexandria and the Book of Tobit. Moreover, the discussion in Mark 12 on the greatest commandment is interpreted as a pleasant encounter in dialogue between a scribe of Hillel’s School and Jesus. It is argued that this encounter illustrates how a fruitful Jewish–Christian dialogue can be based on the cognate heritage and values of Judaism and Christianity which are rooted in the Schools of Hillel and Jesus. This holds true especially for the way in which both Schools linked the pious way of life to high moral standards and love for one’s fellowmen.
