This article tries to explain the exact meaning of eikon and skia in Heb. 10:1,as well as the relation of this passage with Heb. 8:5 & 9:23-4. Especially, I will scrutinize modern scholars’ contention that the Epistle to the Hebrews was deeply influenced by Platonism of Philo of Alexandria. In this way we will get the following conclusions. 1) Originally not only “skia” but also “eikon” had the meaning of “imitation”,while in the philosophy of Plato these terms were used to denote something contrary to “real entity”. But the meaning of these words changed dramatically in the Hellenistic age. So “skia” as before was used with the meaning of “something contrary to real entity”, while “eikon” came to denote “ideas as the archetype of the universe”. Likewise, in the Epistle to the Hebrews “skia” means “a mere imitation of the archetype(something contrary to the archetype)”, while “eikon” denotes “real entity itself (archetype itself)”. This similarity shows strongly some influence of Philonian(or Platonic) dichotomy in the Epistle to the Hebrews. Nevertheless, according to Philo the reality that heavenly tabernacle symbolizes is a spiritual principle or virtue that can be found in human beings generally, while that of the Epistle to the Hebrews is the recovery of the relationship with God through Jesus Christ. In this regards, the author of the Epistle to the Hebrews escapes clearly from the influence of Philo. 2) The author of the Epistle to the Hebrews does not seem to be strongly influenced by Philo’s philosophy. But he might know at least some thoughts of Hellenized Jews that agreed with Philo. And Evidently he kept the Hellenized Jewish faith in mind, while writing the Epistle to the Hebrews. In other words, the readers that were in the mind of the author of the Epistle to the Hebrews were Jewish Christians, in that they knew well the Old Testament with its sacrificial rites and commandments, nevertheless they already had the Hellenistic understanding of archetype vs. imitation and heavenly things vs. earthly things. To these readers, the author of the Epistle to the Hebrews tries to show the real nature of Jesus Christ, advising them not to forsake the Christian faith.
