Speaking of the Triune God: Christian Defence of the Trinity in the Early Islamic Period

Abstract

The arrival of Muslim rulers who were insistent on the unity of God among Christians who testified to the unity of God in His triune nature introduced a considerable challenge to those Christians who were in the ascendency throughout the Middle East. Now they were on the defensive, needing to stem the movement of members of their own community to Islam which would eventually lead to Muslims becoming the majority. In the period of gradual transfer from majority to minority status Christian theologians attempted both to make their faith in the Trinity intelligible to Muslim intellectuals with whom they debated, and to give reasons to Christians for holding firm to their faith. These theologians are hardly known to the global church of the 21st century and it is the purpose of this paper to make them come alive for Christians who are witnessing to their faith before Muslims in our time in the hope that a contemporary testimony to the Triune God can be encouraged.
