Joseph Shaw, chairman of the Latin Mass Society of England and Wales, told CNA that in his view, the survey results will speak to a positive place for the extraordinary form in the life of the Church.
In a statement, Shaw said: "Assuming the CDF receives reasonably complete responses, comparing reports written in 2010 and in 2020 will show not only a steady growth in the number of celebrations, but an increasing and serene integration of the EF [extraordinary form] into the life of the Church, something attributable in large part to the attitude of the bishops themselves."
"What the older generation of more hostile bishops believed is that with some discouragement priests and people would lose interest in it, but this has not happened," he added.
"On the contrary, their successors are almost always more open-minded, and as time goes on it becomes clearer to younger priests and laity how the old arguments against the EF were often based on flawed scholarship and theological misunderstandings, and that as Pope Benedict noted, the ancient Latin liturgical tradition continues to have value for new generations," Shaw said.
In March the CDF announced that it had issued two decrees giving new Eucharistic prefaces and provision for the optional celebration of more recently named saints in the extraordinary form.
The decree Quo magis provided seven new Eucharistic prefaces for the extraordinary form of the Mass, which may be used for particular occasions, such as votive Masses or the feast days of saints.
The second decree, Cum sanctissima, established a provision for the celebration of the third-class feasts of saints canonized after July 1960, whose memorials were established after the 1962 Roman Missal.
