The semantics of “nature” in the languages of our cultural area shows that it is aimed to illustrate the coming-about of reality in general through the metaphor either of birth and growth of animals and plants or of the imprinting of a similar shape on different beings. The linguistic usage becomes an ideological one when metaphors are taken as a doctrinal ground for the enforcement of ethical and social purposes. In Plato’s philosophy the regularity of natural phenomena is given a distinct moral significance as long as it was performed by the divine Demiurge in order to be a cosmic model for the rule of reason in human life. Since the notion of nature is absent from the Bible, Christian dealing with the issue is largely dependent upon the Platonic subordination of nature to providence, viz. its basic fitting with the ethically qualified order of God’s creation. In this framework arises the Christian distinction in man’s sexual behaviour as to its being in accordance with or against nature (though homosexuality was never seen as such in the Greek culture) and the location of God outside the nature; thence also the problem whether God’s supernatural intervention in the world transgresses the natural laws he himself has imposed.
