Contemporary Catholic theological debate on catholicity claims to recover a qualitative conception of catholicity, in order to correct the classical emphasis on geographical breadth. The tendencies to identify catholicity with universality, to confuse universality with uniformity and to equate continuity with immutability, prevented the Church from developing a holistic approach to catholicity. In facing the challenge of globalization, Christianity can offer an alternative way of togetherness in diversity, which seems to be the current translation of the theological category of the catholicity of the Church. This article’s focus will be therefore on the role and significance of community building and the Church’s unity in regard to sustaining creation and addressing globalization.
