Issues

The Greek word Logos (λόγος) is traditionally translated as “Word.” French translations sometimes use “Verb” which has a dynamic quality. The English “Message” or “Expression of the Mind” may also be appropriate attempts to convey the nuance of the Greek concept. The Jewish-Alexandrian theologian and philosopher Philo
Philo
Philo , known also as Philo of Alexandria , Philo Judaeus, Philo Judaeus of Alexandria, Yedidia, "Philon", and Philo the Jew, was a Hellenistic Jewish Biblical philosopher born in Alexandria....

 wrote extensively about the Logos in ways that are reminiscent of New Testament theology. For instance, his teaching that “For the Logos of the living God being the bond of every thing, as has been said before, holds all things together, and binds all the parts, and prevents them from being loosened or separated” echoes Colossians 1:17.

Personhood of the Holy Spirit

Dominating the secular intellectual milieu in which the Cappadocians lived was Platonism, which, when mixed with unreflective Christian theology, bred Arianism, the most prominent heresy at the dawn of the fourth century. According to Platonism, the One or “first cause” radiated immaterial and material entities in a hierarchical, categorized way. If this conceptualization had remained unchecked, the Christian God could have been given a Platonic veneer: the Father as the “first cause,” the Son or Logos as the primary emanation from the One, and the Spirit as a further emanation of the Logos. Arianism held that the Son of God was a being created by the First Person and could not be considered divine, an attractive option incorporating both classical Greek thought and the historical event of the person of Jesus. The Cappadocians vehemently argued against Arianism for its inequality among the divine Persons: “This was the disease of Arius, who gave his name to the madness, and who threw into confusion and brought to ruin a great part of the Church. Without honoring the Father, he dishonored what proceeded from Him by maintaining unequal degrees in the Godhead. But we recognize one glory of the Father, the equality of the Only-begotten, and one glory of the Son, the equality of the Holy Spirit. And we believe that to subordinate anything of the Three is to destroy the whole” (Gregory of Nazianzus, On St. Basil, par. 30.). The Cappadocian insistence on equality among the divine Persons was also a solid refutation of the hierarchical ordering of the cosmos found in Platonism.

According to a belief related to Arianism, Anomoianism, the Spirit was subjugated to the Father and the Son. As time went on, arguing for the divinity of the Spirit became increasingly more important to the Cappadocians. Nicaea left rather open the question of the divinity of the Spirit; belief “in the Holy Spirit” was all the bishops had stated. Advocating for the divinity of the Holy Spirit was crucial for the Cappadocians exactly because of their insistence on the unity and equality of the Three: “The central thrust of Basil’s positive argument in favor of the Spirit’s deity is the non-separability of the three persons and the inference from this that they are all three worthy of this same honor” Anthony Meredith, The Cappadocians (Crestwood, New York: St. Vladimir’s Seminary Press, 1995), 32).

The Cappadocians’ insistence on three co-equal divine Persons, however, subjected them to accusations of tritheism. The extreme opposite, Sabellianism, also widespread at that time, conflated the three Persons into one and saw no distinctions among them whatsoever. The theologians, therefore, had to articulate the unity of the divine essence as well as the distinctness of Persons in the Godhead.

As time went on and in response to continual controversy, the Cappadocians’ theological writings increased in nuance and also in clarity. What emerged from them was the orthodox Christian belief that God is a unity of Three distinct yet inseparable and equal Persons. The Cappadocian theologians worked out this theology by establishing the distinctness of the divine Persons, the communitarian relationships of the Three, and the unity of their divine essence.
