8.2 The World Communicates Contextual Outline Humans are social animals and have successfully communicated through the spoken word‚ and then‚ as the use of written codes developed‚ through increasingly sophisticated graphic symbols. The use of a hard copy medium to transfer information in coded form meant that communication was able to cross greater distances with improved accuracy of information transfer. A messenger was required to carry the information in hard copy form and this carrier could

Christianity Principle Beliefs Outline the principal beliefs regarding the divinity and humanity of Jesus Christ The Christological controversies of the fourth and fifth centuries were debates regarding the nature of Christ‚ and in particular the issue of his humanity versus his divinity. Docetism is a position which undermines the integrity of the humanity of Jesus because it claims that Jesus is fully divine but not truly human‚ because he is God merely adopting the appearance of being human
