Tertullian

“ You find Paul confessing his faith before the chief priests, under the shelter of the chief captain, [4] among the Sadducees and the Pharisees: “Men and brethren,” he says, “I am a Pharisee, the son of a Pharisee; of the hope and resurrection of the dead I am now called in question by you,” [5] —referring, of course, to the nation’s hope; in order to avoid, in his present condition, as an apparent transgressor of the law, being thought to approach to the Sadducees in opinion on the most important article of the faith—even the resurrection. ”

“ They had, in fact, derided his announcement; but they would have indulged no such derision if they had heard from him nothing but the restoration of the soul, for they would have received that as the very common anticipation of their own native philosophy. ”
