The article presents the Christology of Paul Tillich in his Systematic Theology with the aim of explaining his theological conception in relation to orthodoxy. In the first part of the article, there are sketched the main events of Tillich's life. In the second part, the reader is informed about 'Systematic Theology' in general. In the third part the author of this article follows the Tillich's work on some basic themes of Christology. He finds that Tillich takes an adoptianistic conception of Jesus as the Christ who is made capable by God of becoming the New Being and who is accepted by disciples in this way. Although various important implications of the revelatory and redemptive signification of the Christ's divine nature are absent his Christology shows many prophetic accents and intuitions which were successfully developed in theology later.
