<P> The doctrines of the apostles of Jesus brought the Early Church into conflict with some Jewish religious authorities (Acts records dispute over resurrection of the dead which was rejected by the Sadducees, see also Persecution of Christians in the New Testament), and possibly later led to Christians' expulsion from synagogues (see Council of Jamnia for other theories). While Marcionism rejected all Jewish influence on Christianity, Proto - orthodox Christianity instead retained some of the doctrines and practices of 1st - century Judaism while rejecting others, see the Historical background to the issue of Biblical law in Christianity and Early Christianity . They held the Jewish scriptures to be authoritative and sacred, employing mostly the Septuagint or Targum translations, and adding other texts as the New Testament canon developed . Christian baptism was another continuation of a Judaic practice . </P> <P> Before his conversion, Paul persecuted the Jewish Christians as a heretical sect, such as the martyrdom of Stephen . After his conversion, he assumed the title of "Apostle to the Gentiles" and actively converted gentiles to his beliefs, known as Pauline Christianity . Paul's influence on Christian thinking arguably has been more significant than any other New Testament author . Augustine (354 - 430) developed Paul's idea that salvation is based on faith and not "works of the law". Luther (1483--1546) and his doctrine of sola fide were heavily influenced by Paul . Evangelical Christians refer to the Romans road, an explanation of the Gospel of Jesus Christ taken solely from the book of Romans, using esp . Romans 3: 23 and Romans 6: 23, which indicate, respectively, the need of each person for God's forgiveness and God's gift of that forgiveness through Jesus . </P> <P> Recently, Talmudic scholar Daniel Boyarin has argued that Paul's theology of the spirit is more deeply rooted in Hellenistic Judaism than generally believed . In A Radical Jew, Boyarin argues that Paul combined the life of Jesus with Greek philosophy to reinterpret the Hebrew Bible in terms of the Platonic dualist opposition between the ideal (which is real) and the material (which is false). </P> <P> While Jewish accounts suppose that Gamaliel remained a Pharisee, an early ecclesiastical tradition suggests that he embraced Christianity but remained in the Sanhedrin to secretly assist other Christians. . Photius also records Peter and John baptizing Gamaliel . </P>
