The Old Paths by Alexander McCaul is a theological critique of Rabbinic Judaism, originally published in the 19th century. The book examines the Talmudic traditions and compares them to the teachings of Moses and the Prophets in the Hebrew Bible. McCaul argues that modern Judaism has deviated from its original foundations and presents Christianity as the fulfillment of Jewish teachings. The work is structured as a series of essays, each addressing different aspects of Jewish law, customs, and beliefs. McCaul critiques Rabbinic authority, the treatment of women and Gentiles, and the concept of salvation within Judaism. His analysis is framed within a Christian missionary perspective, aiming to demonstrate the superiority of Biblical Christianity over Rabbinic traditions.
