Unit rationale, description and aim

This unit investigates the doctrine of the Trinity and its centrality to Christian faith and life. The scriptural foundations of the doctrine of the Trinity will be explored.. The doctrine's development including key patristic debates, will be examined. Key Trinitarian theologies will be evaluated, from Augustine and Aquinas to Barth and Rahner. Finally, various theological approaches to the revealed mystery of God will be considered in the light of contemporary worldviews and interfaith dialogue.

The aim of the unit is for students to show an understanding of Trinitarian theology by explaining and evaluating significant perspectives, methods, and issues in this area, in the light of contemporary and historical contexts. Moreover, this unit will assist students to develop a critical understanding of the relevance and implications of Trinitarian belief to the life of individual Christians, the church and diverse contexts.

Learning and teaching strategy and rationale

This unit involves 150 hours of focused learning, or the equivalent of 10 hours per week for 15 weeks. The total includes formally structured learning activities such as lectures, tutorials, online learning or supervision. The remaining hours typically involve reading, research, and the preparation of tasks for assessment.

The unit is normally offered in attendance mode or multi-mode. Students learn through formally structured and sequenced learning activities that support the achievement of the learning outcomes. Students are asked to critically reflect, analyse, and integrate new information with existing knowledge, draw meaningful new connections, and then apply what they have learned. Collaborative and peer learning is also emphasised.

THCT213 emphasises students as active, adult learners. Students are recognised as adult learners who engage best when what they are learning is relevant to them and gives them the opportunity to be responsible for their own learning. In many ways, the student is the one who drives the learning forward, and their active participation in this unit is essential. Learning is designed to be an engaging and supportive experience, which helps students to develop critical thinking and reflection skills.
