Abstract
This article is a critical engagement with D. Stăniloae’s and J. Ratzinger’s ecclesiological thought as shaped by the description of church as the body of Christ and the Trinitarian roots of this ecclesiology. Starting from practical problems of prayer and living a Christian life, the authors argue that God’s relationship to the Christian community has primacy over God’s relationship to individual believers. When one conceives of the Christian community as being the body of Christ, one can uphold the elevated Christian ideal of Eucharist Communio without making it unattainable. The authors show that the being of the church is given to the Christian community not as a possession or property, but as a task to be fulfilled through the power of Christ and of the Holy Spirit. One can discover that in becoming the church, the Christian community is elevated to the Trinitarian life in communion. Communion ecclesiology has the potential to bridge the divide between the Orthodox and Catholic churches.
