Antonio Piñero’s Orígenes del Cristianismo presents early Christianity as a complex "mosaic" of multiple, distinct groups rather than a single, linear progression, arguing that Jesus was a profoundly Jewish figure rather than the founder of a new religion. The work explores how early followers interpreted Jesus's life, heavily incorporating Persian, Jewish, and Hellenistic philosophies to form a new faith.
