To say that the Eucharist does in fact realize the body of Christ is not in any way to idealize the church as institution or those who hold authority in it. [The] church militant is always flawed and sinful. Although inseparable, the church militant is not simply identical with the church triumphant as realized in the liturgy. In the Eucharist the church is always called to become what it eschatologically is. The Eucharist does make the church ex opera operate, but the effects are not always visible due to human sin. Christians are called to conform their practice to the Eucharistic imagination. And […] to use the term ‘imagination’ is not to imply unreality. Rather the Eucharistic imagination is a vision of what is really real, the Kingdom of God, as it disrupts the imagination of violence. (William T Cavanaugh, Torture and Eucharist, p.206)
