The Gospel Procession
While the Gospel Acclamation is being sung, other things are happening.
If incense is to be used, the thurible and the boat are brought to the presider, and he adds incense to the thurible. The procession to the ambo can be accompanied by candles and incense (though at Holy Spirit it only sometimes accompanied by incense and rarely with candles.)
If a priest alone is celebrating the Mass, he approaches the altar, bows and prays quietly,
Cleanse my heart and my lips, almighty God,
that I may worthily proclaim your holy Gospel.
There is a long-standing practice in the Church that the presider does not proclaim the Gospel, but it is proclaimed by another cleric. If a deacon is present, he approaches the celebrant and says:
Your blessing, Bishop/Father.
The bishop or priest says, making the sign of the cross over the deacon,
May the Lord be in your heart and on your lips
that you may proclaim his Gospel worthily and well,
in the name of the Father and of the Son and of the Holy Spirit.
If no deacon is present at a Mass with the bishop and another priest is present, the priest asks for and receives the blessing in this way. If there are only priests concelebrating without a bishop or a deacon, another priest than the presider proclaims the Gospel, but does not ask for the blessing of the presider, but approaches the altar and prays the prayer said by the priest alone celebrating the Mass.
After the prayers, the priest/deacon takes the Book of the Gospels from the altar and carries it in procession to the ambo. The book is to be the Book of the Gospels, which has only the Gospels for the Liturgical cycle and not the Old Testament readings/Psalms/New Testament readings contained in the Lectionary.
The procession with the Book of the Gospels arrives at the ambo for the proclamation of the Gospel.
