More than just a mere twice. Look at the huge dispute between the modernists and the reactionaries in the RCC over whether one must be in the Church to be saved. Is that "faith" or a "work"?Of course they have. Twice, in fact. The Catholics determined that both faith and works were required, while the Protestants determined that faith alone was how people were to be saved.
Most Gnostics took the opposite view, and were strongly opposed to Judaism, because it promoted the evil creator of the world as the Chief God, which Gnostics denied.There's even more....According to the NT Scholar Bart Ehrman, the Gnostics had the notion that the OT God was an insane rogue god, and that JC's real purpose was (by way of his "secret knowledge") to show people the way back to the REAL gods.
But not everybody....Only those with the "spark of the divine". I suppose this could be construed as the Children Of Israel....But I don't believe there were any instructions for determining who had the spark...
