Project BLACK MAMBA: Lent

'Tis the Optional Memorial of Saint Patrick, Bishop (circa 386-464): Saint-link ūnus, Saint-link duo, & Wikipedia-link.

Commentary: Wayback Machine. Quoth the Holy Redeemer bulletin:

There is broad agreement that Patrick was active as a missionary in Ireland during the second half of the fifth century. Early medieval tradition credits him with being the first bishop of Armagh & Primate of Ireland, & they regard him as the founder of Christianity in Ireland, converting a society practicing a form of Celtic polytheism.

'Tis also the festival of Blessed Conrad of Bavaria, Religious, O.Cist. (circa 1105-1154): Blessed-link & Wikipedia-link.

'Tis also the festival of Saint Jan Sarkander, Priest & Martyr (1576-1620), martyred by Protestants for refusing to break the seal of the confessional: Martyr-link & Wikipedia-link.

Commentary: Quoth the missalette from World Library Publications:

During Lent is a memorial is observed by a community, the Collect of the memorial may replace the Collect of the Lenten weekday or be used as the concluding prayer of the Prayer of the Faithful. All other Mass texts, including the readings, are taken from the Lenten weekday. The vesture is violet.

So why the alternate readings for the Optional Memorial of St. Patrick?
