Today is the first time the Church prays the Mass for the liturgical memorial of Blessed John Paul II. To date, Blessed John Paul II's feast is observed in the USA as an optional memorial. The US Conference of Bishops is requesting of the Holy See that this feast be an obligatory liturgical memorial. The second reading for the Office of Readings is here. Other texts for Mass and the Divine Office are taken from the "Common of Pastors: For a Pope."
The Collect (opening prayer for Mass) is given here in English and Latin:
O God, who are rich in mercy and who willed that the Blessed John Paul II should preside as Pope over your universal Church, grant, we pray, that instructed by his teaching, we may open our hearts to the saving grace of Christ, the sole Redeemer of mankind. Who lives and reigns.
Deus, dives in misericórdia, qui beátum Ioánnem Paulum, papam, univérsae Ecclésiae tuae praeésse voluísti, praesta, quaésumus, ut, eius institútis edócti, corda nostra salutíferae grátiae Christi, uníus redemptóris hóminis, fidénter aperiámus. Qui tecum.
