Abstract
Thomas Aquinas anthropology is related to the description of human nature, which was established at the beginning, before original sin, as well as taking into account all its effects, and the nature that was united with God. The distinction of two intellects adopted by Aristotle - a potential and active intellect - for Aquinas was helpful in showing the unique character of the knowledge that Adam and Christ had. Adam as the one who was appointed as teacher of people, had perfect knowledge and did not have a potential intellect that would be an unwritten tablet. His potential intellect had the habits of knowledge, by which he had a perfect knowledge of everything that can be embraced in any field of cognition by the power of the first principles of knowledge. The perfection of Christ's knowledge was incomparably greater than knowledge of Adam and every other human being – it was result of unification with the Word, but not the mixing of two natures. Christ had knowledge which have blessed (saved), infused knowledge (resulting from union with the Word) and had experiential knowledge appropriate to age and time. Christ developed in knowledge and wisdom because he grew in human experience.
