A kind friend sent me this message which he received from the USCCB:

Conversion of Saint Paul (January 25, 2009) • In observance of the Year of St. Paul, Pope Benedict XVI has granted
permission to observe the Feast of the Conversion of St. Paul on Sunday this year; normally this feast would not be observed when it falls on a Sunday.

Parishes may celebrate the Third Sunday in Ordinary Time or they may observe the Feast of the Conversion of St. Paul with its proper texts from the Roman Missal (using the Preface of Apostles I or II) and the Lectionary for Mass (no. 519). In addition, the recitation of the Creed is included, and because there are only two readings provided in the Lectionary for Mass, the second Reading of the Third Sunday in Ordinary Time is used.
