From the St. Louis Review:
A procession around the block will follow Mass at 5 p.m. June 14 at the Cathedral Basilica of St. Louis, Lindell Boulevard and Newstead Avenue.From Saint Francis de Sales Oratory:
The procession will begin on the front plaza of the cathedral basilica, move west along Lindell Boulevard, north on Taylor Avenue, east on Maryland Avenue and south on Newstead Avenue before returning to the cathedral basilica.
Along the route, Benediction of the Blessed Sacrament will be celebrated at three outdoor altars. The first will be at the archbishop’s residence, on the southwest corner of Lindell Boulevard and Taylor Avenue. The second will be at the cathedral convent, 4440 Maryland Ave., adjacent to Cathedral School. The third will be on the grounds of Cathedral Tower, 325 N. Newstead Ave., one block north of the cathedral basilica.
Benediction will be celebrated a fourth time when the procession returns to the cathedral basilica.
On Sunday, June 14, the Oratory will celebrate the External Solemnity of the feast of Corpus Christi. The Solemn High Mass at 10 am of that day will again culminate in a solemn procession with the Blessed Sacrament through the streets surrounding the Oratory. It is especially this feast which manifests publicly the central importance of the Eucharist. During our procession we bring the Lord to the world, to announce the presence of Christ in this world. Corpus Christi – the feast of the Eucharist which echoes the mystery of Holy Thursday in the splendor of the Church’s liturgy. After Pentecost and the establishment of the Church the celebration of the Eucharist has a public character.Click here for a listing of churches in the Archdiocese having processions.
