On the Holy Spirit

Written in the Spirit on the Spirit

The superlative treatise on the Divinity of the Third Person of the Trinity.

“Whenever I read Basil’s work on the Spirit, I find the God Whom I possess, and grow bold in speaking the truth, thanks to the support of his theology and spiritual vision. I proceed from one depth to another, calling upon deep after deep, and finding light after light, until I attain the highest pinnacle!” —Saint Gregory the Theologian
