Who is Theophilos, whom St. Luke addrssed Acts too?

Not just Acts, he also addressed his gospel to him (Luke 1: 3 & 4)

Apparently a christian as Luke was trying to assure him of what he had learned prior. Other than that, little is known. The way he addressed him may indicate that Theophilos had a position of some kind, but it isn't know for certain.

Hello,

'Insight on the Scriptures states:

*** it-2 p. 1990

THEOPHILUS

(The·oph′i·lus) [Loved by God; Friend of God].

The person to whom Luke addressed both his Gospel and the Acts of Apostles. (Lu 1:3, 4; Ac 1:1) His being called “most excellent” may indicate a high position of some kind, or it may simply be an expression of high esteem. Theophilus apparently was a Christian, having been orally taught about Jesus Christ and his ministry. Luke’s written statement served to assure him of the certainty of what he had learned previously by word of mouth.

Kind regards, Günter

No one knows for certain. See the Wikipedia page here: http://en.wikipedia.org/wiki/Theophilus_(biblical)

This was the only Theophilus that I could find.
