Paul does not locate the death and resurrection of Christ on earth or in history. According to him, the crucifixion took place in the spiritual world, in a supernatural dimension above the earth, at the hands of the demon spirits (which many scholars agree is the meaning of "rulers of this age" in 1 Corinthians 2:8). The Epistle to the Hebrews locates Christ’s sacrifice in a heavenly sanctuary (ch. 8, 9). The Ascension of Isaiah, a composite Jewish-Christian work of the late first century, describes (9:13-15) Christ’s crucifixion by Satan and his demons in the firmament (the heavenly sphere between earth and moon). Knowledge of these events was derived from visionary experiences and from scripture, which was seen as a ‘window’ onto the higher spiritual world of God and his workings.
