Based upon his newfound understanding of the Bible, Thomas was rebaptised (a third and final time) in 1847 and the groups of and individuals who shared his beliefs continued to grow. In 1848 the movement became international when he travelled to England in order to preach what he now saw as the true gospel message. Upon his return to America, Thomas moved from Richmond, Virginia to New York City and began to preach there. He made a point of speaking to the Jewish community because Dr Thomas had come to believe that Christianity did not replace the Law of Moses but rather fulfilled it. He believed that Christians must, though faith and baptism, become the "seed" (or, "descendant") of Abraham.
