He studied philosophy and theology in Erlangen, Halle and Berlin, and as a student had renowned instructors that included Friedrich Schleiermacher, August Neander, G. W. F. Hegel, Philip Marheineke and Friedrich Tholuck. In 1829 he began serving as a pastor in Nuremberg, and in 1842 was appointed professor of dogmatics at the University of Erlangen.

Thomasius was an important representative of the "Erlangen School" within the German Neo-Lutheranism movement and a major influence on, for instance, the church historian Albert Hauck. He is remembered for introducing the concept of Kenotic Christology into German theology, of which his aim was to provide an understanding of the limited consciousness of Jesus Christ, without denying the unity of deity and humanity in Christ.
