Jurnal Teologi Reformed Indonesia 7/1 (Januari 2017): 33-42 33 Grace, the Holy Spirit, and Love Comparing the Thoughts of St. Augustine, Peter Lombard, and William of St. Thierry Hans Harmakaputra Abstrak Warisan teologis tentang hubungan antara anugerah, Roh Kudus, dan kasih dikembangkan dan diperkaya pada era Pertengahan oleh tiga sosok penting, Agustinus, Peter Lombard, dan William dari St. Thierry. Namun, isu-isu kontekstual menyebabkan ketiga teolog ini memiliki aksentuasi yang sedikit berbeda satu sama lain. Esai ini akan pertama-tama menampilkan korelasi antara anugerah, Roh Kudus, dan kasih di dalam pemikiran mereka, kemudian menyediakan perbandingan analitis dari pelbagai kesamaan dan perbedaan yang ada. Kata-Kata Kunci: Agustinus, Roh Kudus, anugerah, kasih, Peter Lombard, William dari St. Thierry Abstract Theological heritage on the relationship between grace, Spirit, and love was developed and enriched in the medieval era by three important figures, Augustine, Peter Lombard, and William of St. Thierry. However, these theologians have slightly different accents due to contextual issues. This essay will first show the correlation between grace, love, and the Holy Spirit in their thoughts, and then I will provide an analytical comparison regarding their similarities and differences. Keywords: Augustine, Holy Spirit, grace, love, Peter Lombard, William of St. Thierry Augustine is a figure who established the importance of the doctrine of grace in Christ- ian theology and set a firm standard for further developments of later Christian tradi- tion. Grace is indispensable, Augustine argued, for human salvation because humans cannot save themselves due to their natural state of sin. The Holy Spirit and love are connected very closely with grace in Augustine’s scheme. The Augustinian tradition of grace had dominated Christian theological discourse for several hundred years before Thomas Aquinas changed the discussion in an entirely different direction. Unlike Augustine, Aquinas teach- ing on grace is built upon the Aristotelian philosophy that divides “natural” and “super- natural.” During the years between Augustine and Aquinas, the primary interpreter for Augustinian teaching on grace is Peter Lombard, whose Book of Sentences had been the main source of theological education in universities. Lombard is famous for his identification of grace with love and the Holy Spirit. Another figure who lived as contem- porary of Lombard is William of St. Thierry.
