The aim of this paper is to contribute to the project of recovering aspects of Christian thought which are significant for a contemporary eco-theological sensibility. The work of William Temple, in particular his concept of the sacramental universe, is discussed in relation to three eco-theological principles. Temple’s affirmation that matter has significance coheres with the principle that the Earth has value; his notion that the Incarnation is the pre-eminent expression of divine meaning connects with the principle that creation is expressive of divine mind and purpose; and the inter-disciplinary scope of Temple’s thought coheres with the principle of inter-connectedness. Temple’s concept of the sacramental universe might assist the engagement between theology and the present ecological context.
