Through mighty signs and wonders, by the power of the Spirit of God; so that from Jerusalem, and round about unto Illyricum, I have fully preached the gospel of Christ.
Read Chapter 15
Ignatius of Antioch
AD 108
For ye are the fellow-citizens as well as the disciples of Paul, who "fully preached the Gospel from Jerusalem, and round about unto Illyricum"
Count up all the places Paul had been—not just in the Roman Empire but beyond its frontiers as well. Phoenicia, Syria, Cilicia and Cappadocia for a start, but also the back country—Arabia, Persia and Armenia. This is why he said “as far round as Illyricum,” so that you would not only think of the direct route from Jerusalem to Illyricum but consider also all the surrounding countries as well.
