In this volume, the study of the history of the doctrine of the Holy Spirit is carried on from the sub-apostolic writers to the end of the patristic period, which is generally held to terminate with Gregory the Great in the West and John of Damascus in the East. This is an early classic study in doctrinal development by one of the foremost exegetes of the late 19th/early 20th century.

For the Spirit, being somewhat forgotten is an occupational hazard. The Holy Spirit is so actively involved in our lives that we can take his presence for granted. As they say, familiarity breeds contempt. Just as we take breathing for granted, we can take the Holy Spirit for granted simply because we constantly depend on him. Like the cane that soon feels like an extension of the blind man’s own body, we too easily begin to think of the Holy Spirit as an extension of ourselves. Yet the Spirit is at the center of the action in the divine drama from Genesis 1:2 all the way to Revelation 22:17. The Spirit’s work is as essential as the Father’s and the Son’s, yet the Spirit’s work is always directed to the person and work of Christ. In fact, the efficacy of the Holy Spirit’s mission is measured by the extent to which we are focused on Christ. The Holy Spirit is the person of the Trinity who brings the work of the Father, in the Son, to completion. In everything that the Triune God performs, this perfecting work is characteristic of the Spirit. In Rediscovering the Holy Spirit, author, pastor, and theologian Mike Horton introduces readers to the neglected person of the Holy Spirit, showing that the work of God’s Spirit is far more ordinary and common than we realize. Horton argues that we need to take a step back every now and again to focus on the Spirit himself—his person and work—in order to recognize him as someone other than Jesus or ourselves, much less something in creation. Through this contemplation we can gain a fresh dependence on the Holy Spirit in every area of our lives.

Origen’s On First Principles is a foundational work in the development of Christian thought and doctrine: it is the first attempt in history at a systematic Christian theology. For over a decade it has been out of print with only expensive used copies available; now it is available at an affordable price and in a more accessible format. On First Principles is the most important surviving text written by third-century Church father, Origen. Origen wrote in a time when fundamental doctrines had not yet been fully articulated by the Church, and contributed to the very formation of Christianity. Readers see Origen grappling with the mysteries of salvation and brainstorming how they can be understood. This edition presents G. W. Butterworth’s trusted translation in a new, more readable format, retains the introduction by Henri de Lubac, and includes a new foreword by John C. Cavadini. As St. Gregory of Nazianzus, Doctor of the Church, wrote: “Origen is the stone on which all of us were sharpened.”

This classic exposition of Trinitarian doctrine eloquently sets forth the distinction yet perpetual communion of the divine Persons. Without explicitly calling the Spirit "God, " St Basil demonstrates that He, like the Son, is of the same nature with the Father.

The following dissertation concerning the Trinity, as the reader ought to be informed, has been written in order to guard against the sophistries of those who disdain to begin with faith, and are deceived by a crude and perverse love of reason. Now one class of such men endeavor to transfer to things incorporeal and spiritual the ideas they have formed, whether through experience of the bodily senses, or by natural human wit and diligent quickness, or by the aid of art, from things corporeal; so as to seek to measure and conceive of the former by the latter.

What beliefs are core to the Christian faith? This book is here to help you understand the reason for your hope as a Christian so that you can see it with fresh sight and invite others into the conversation. A lot of Christians take their story—the narratives that give rise to their beliefs—for granted. They pray, go to church, perhaps even read their Bible. But they might be stuck if a stranger asked them to explain what they believe and why they believe it. Author, pastor, and theologian Mike Horton unpacks the essential and basic beliefs that all Christians share in a way that is easy to understand and applicable to our lives today. And in a way that will make you excited to be a Christian! Core Christianity covers topics like: Jesus as both fully God and fully man. The doctrine of the Trinity. The goodness of God despite a broken world. The ways God speaks. The meaning of salvation. What is the Christian calling? Includes discussion questions for individual or group use. This introduction to the basic doctrines of Christianity is perfect for those who are new to the faith, as well as those who have an interest in deepening their understanding of what it means to be a follower of Jesus Christ.

Augustine, the man with upturned eye, with pen in the left hand, and a burning heart in the right (as he is usually represented), is a philosophical and theological genius of the first order, towering like a pyramid above his age, and looking down commandingly upon succeeding centuries. He had a mind uncommonly fertile and deep, bold and soaring; and with it, what is better, a heart full of Christian love and humility. He stands of right by the side of the greatest philosophers of antiquity and of modern times. We meet him alike on the broad highways and the narrow footpaths, on the giddy Alpine heights and in the awful depths of speculation, wherever philosophical thinkers before him or after him have trod. As a theologian he is facile princeps, at least surpassed by no church father, schoolman, or reformer. With royal munificence he scattered ideas in passing, which have set in mighty motion other lands and later times. He combined the creative power of Tertullian with the churchly spirit of Cyprian, the speculative intellect of the Greek church with the practical tact of the Latin. He was a Christian philosopher and a philosophical theologian to the full.
