An emotional God
The Bible is rich in emotions of every sort and every intensity.1 From the most violent to the most subtle, from the most noble to the most vile, they abound in its historical and prophetic books and saturate those of poetry and wisdom (the Psalms, the Song of Songs, the Wisdom of Sirach). These latter texts were given pride of place in the meditations of medieval intellectuals, especially those in religious orders. The emotions described in the Scriptures are not solely those of humans, but also those of God. The God of the Bible was neither unemotional nor impassive – especially in his often tumultuous relations with his people. The Old Testament overflows with situations where the wrath of God is palpable: ‘Therefore the Lord heard, and was angry; a fire was kindled against Jacob, and wrath came up against Israel’ (Ps 77: 21).2 In return, this irascible God could also show mercy and let himself be moved: ‘But he is merciful, and will forgive their sins: and will not destroy them. And many a time did he turn away his anger: and did not kindle all his wrath. And he remembered that they are flesh: a wind that goeth and returneth not’ (Ps 77: 38–9). The image here is of a wrathful God rendered suddenly tender, almost hesitant, by the fragility of his creation.
In the New Testament, divine wrath is likewise present. The advent of God made man in the person of Jesus changed everything, however.3 More than his Father, Jesus overflowed with emotions that he sought neither to hide nor to neutralize, since they were signs of his own humanity. Christ, God made flesh, thus experienced compassion, fear, love, and pity. He felt no jealousy, envy, or hate. Rather his emotions were virtuous, contributing to salvation but also to just wrath. On the Mount of Olives on the eve of his death, Jesus’ anguish and pain were so intense that an angel came to comfort him (Luke 22: 42–3). He wept for the fate of Jerusalem before bringing his full wrath to bear against the merchants of the Temple, whom he ruthlessly expelled (Luke 19: 41). By contrast, the canonical Gospels are less inclined to evoke Christ's emotions during the Passion, beyond his famous cry of anguish: ‘My God, my God, why have you forsaken me?’ (Mark 15: 34; Matt. 27: 46). How did Jesus experience the outrages and humiliations he suffered? Did he feel shame or indignation when faced with the jibes and spitting of the crowd? Did he suffer in spirit over and above the physical pain that he had to endure during his ordeal? In paradise, did he continue to suffer as a man for the sins of humanity? The authors of the Middle Ages posed all of these questions. They were especially crucial in so far as they determined the very nature of God, and the writers developed specific responses to them. During his corporeal life, Jesus was able to feel all of the virtuous emotions as a man, from the sweetest to the most painful. On the other hand, if the resurrected Jesus continued to feel emotions, these were experienced in a non-carnal – and thus non-human – manner. He could thus no longer shed tears, however great his pain.4
The first and foremost commandment of the Gospels is the commandment of love: ‘Thou shalt love the Lord thy God with thy whole heart, and with thy whole soul, and with thy whole mind’ (Matt. 22: 37); ‘This is my commandment, that you love one another, as I have loved you’ (John 15: 12); ‘Love your enemies: do good to them that hate you: and pray for them that persecute and calumniate you’ (Matt. 5: 44). To love God, to love oneself, to love one's neighbour, to love one's enemies: such is the order of love – both in the sense of injunction and of hierarchy – which ought to preside over the social life of man and his ties to God. When Western Christians received the message of the Gospel, they identified this commandment with a specific form of love: ‘charity’. Jerome used caritas to translate the Greek agapè, a term which described a measured and impartial attachment that engaged every aspect of one's being, including both reason and the will. This love could be distinguished from amor – erôs in Greek – without necessarily being opposed to it. The latter term implied longing, a drive to possess something, whether spiritual or material, that was often irrepressible.5 Described as an encompassing and inclusive embrace, the love found in charity was meant to expand outwards, without excess or passion: it called for the care of one's neighbour as well as oneself. The love described by amor, however, was an intense state of feeling which picked its target and plunged towards it, like a hunter's spear towards its prey. It was a hazardous, exclusive, and violent experience. As such, it galvanized mystics, pulling them wholly towards God and creating an inseparable bond, while blinding the greedy, who remained ensnared in worldly desires.
The theologians of these first Christian centuries also used the word dilectio to describe the love that emanated from the spirit and the soul. Its meaning was very close to caritas, but more personal: the term was related to electio, choice.6 If the term caritas was not unheard of in pagan Latin – Cicero includes it within the family of virtues upon which social life was founded – this dilectio was absent. The duty of Christian love proved a fitting substitute for the Roman ethical value of fides, i.e. trust in one's word and in the law. ‘Trust’ configured as ‘faith’ developed into ‘love’. For Paul, this ‘commandment of love’ – a neat expression of this new alliance – subsumed the Mosaic Law: ‘Love [dilectio] is the fulfilment of the Law’ (Rom. 13: 10). St John completed this emotional revolution. He bound the Law and God himself together to form a conclusion that contained the quintessence of Christianity in the medieval West: ‘God is charity: and he that abideth in charity, abideth in God, and God in him.’ God was not only endowed with emotions: he was himself the emotional force of love.
God's wrath: a proof of his existence
For the most part, the Latin theologians of these first Christian centuries were educated in the schools of the Empire. From Tertullian (d. c. 220) through to Augustine, all the Latin Fathers – a list that includes Lactantius (d. c. 320), Ambrose of Milan (d. 397), Arnobius (d. early fourth century), and Jerome – had a solid formation in classical culture.7 Some, like Lactantius and Augustine, had even been masters of rhetoric and philosophy before devoting their life and their quills to their new faith. Christian theology did not emerge by spontaneous generation: it was deeply anchored in the Scriptures but also nourished by pagan culture, especially the immense Greco-Roman philosophical heritage. This was a great accumulation of thought, beginning with Socratic philosophy and continuing through to the Neo-Platonic thought of Plotinus, the Peripatetic school, and the Stoicism of the late Empire.8 For these philosophical schools, however, the mere mention of a God capable of wrath was nonsensical. Wrath was a passion, and as such, a deviation from reason. God, the prime mover, was by nature apathès, and thus devoid of all passion. This doctrine of divine apatheia, an impassivity which the Latins sometimes called tranquilitas, the tranquillity of the soul, was essential. Nevertheless, impassivity, the absence of passions, did not necessarily mean insensibility, the incapacity to feel emotions or an indifference towards them. How rigid these philosophical conceptions were depended on the school. The disciples of Aristotle were less dismissive of such possibilities than the Stoics, for whom God was a being of pure reason: for them, certain palpable emotions, such as measured joy, could be considered compatible with apatheia.
Greek theologians, greatly influenced by Stoicism, did not seek to break from philosophical tradition on this point. They...
