Bithynia: A province in Asia Minor, to the south of the Euxine and Propontis.
Christian congregations were here formed at an early time
(1 Peter 1:1)
Paul was prevented by the Spirit from entering this province
(Acts 16:7)
It is noted in church history as the province ruled over by Pliny as
Roman proconsul, who was perplexed as to the course he should take
with the numerous Christians brought before his tribunal on account
of their profession of Christianity and their conduct, and wrote to
Trajan, the emperor, for instructions (A.D. 107)
