Theophilus (Greek: Θεόφιλος) is the name or honorary title of the person to whom the Gospel of Luke and the Acts of the Apostles are addressed (Luke 1:3, Acts 1:1). It is thought that both works were written by the same author, and often argued that the two books were originally a single unified work.[1] Both were written in a refined Koine Greek, and the name Θεόφιλος (Theophilos), as it appears therein, means friend of God[2] or (be)loved by God or loving God[3] in the Greek language. The true identity of Theophilus is unknown, with several conjectures and traditions around an identity. In English Theophilus is also written "Theophilos", both a common name and an honorary title among the learned (academic) Romans and Jews of the era. The life of Theophilus would coincide with the writing of Luke and the author of the Acts.
