This book bridges Catholic and Protestant theologies of the eucharist using ritual practice and the act of giving thanks.

All doctrinal development and debate occurs against the background of Christian practice and worship. By attending to what Christians have done in the eucharist, Kimberly Belcher provides a new perspective on the history of eucharistic doctrine and Christian divisions today. Stepping back from the metaphysical approaches that divide the churches, she focuses on a phenomenological approach to the eucharist and a retrieval of forgotten elements in Ambrose's and Augustine's work. The core of the eucharist is the act of giving thanks to the Father – for the covenant and for the world. This unitive core allows for significant diversity on questions about presence, sacrifice, ecclesiology, and ministry. Belcher shows that the key is humility about what we know and what we do not, which gives us a willingness to receive differences in Christian teachings as gifts that will allow us to move forward in a new way.
