There was nothing called “Christianity” in the first century, only groups of people who believed that Jesus of Nazareth was Israel’s Messiah and the world’s rightful Lord. There was nothing corresponding to what we now call “Judaism” in the first century (the word then, as we saw, had an active force meaning “the zealous propagation of the Jewish way of life”), only the many communities of Jews around the world, praying to Israel’s God, studying the scriptures, focusing on Temple and Torah.
