The Nicene Age

Who Eustathius of Sebaste was

The magnetic ascetic who first drew Basil to the monastic life — and broke his heart: condemned at Gangra for his extremists, restless through every creed of the age, he ended denying the Spirit's divinity, and Basil's On the Holy Spirit answers, without naming, the mentor of his youth.

Also listed in bishops beyond the great sees and desert fathers & mothers.

Letter 223 (against Eustathius)

c. AD 375
I spent much time on vanity… then I read the Gospel, and saw that the great means of perfection was the selling of one's goods. And finding certain men in my own country attempting to copy that citizenship — much I conversed with Eustathius, and loved him. What has now become of those hopes, God knows.
