Abstract
In studying those issues that separate the Eastern and Western churches and prevent reciprocal eucharistic hospitality most attention is devoted to precise matters of doctrine that have become contested over time. This paper argues that there are larger issues of theological approach which prevent progress in dialogue and mutual understanding. While Westerners focus on history as the underpinning of doctrine, Easterners focus on eschatology as its “completion.” But both sides should note that neither approach can grasp the reality of ‘the present’ which is the moment of liturgical action. Noting these divergent perspectives may enrich dialogue; while acknowledging their respective limits may provide a way through the current impasse.
