In the liturgy of the ancient Church, after the homily the Bishop or the one who presided at the celebration, the principal celebrant, would say: "Conversi ad Dominum". Then he and everyone would rise and turn to the East. They all wanted to look towards Christ. Only if we are converted, only in this conversion to Christ, in this common gaze at Christ, will we be able to find the gift of unity.
