In his Herald article written in Cebuano, he discusses how the Misa ng Bayang Pilipino was presented and approved by the Sacred Congregation for Divine Worship and the Discipline of the Sacraments on August 10, 1976!
A quick check on the Acta Apostolica Sedis renders NOTHING. No act from the Sacred Congregation about the MBP is there! You can view the AAS report for 1976 here.
And if you look at the online copy of the missalette of the Misa ng Bayang Pilipino during the PCNE, you can see that Fr. Diwa ADMITTED that this rite did not get the approval of the Holy See.
So, how do we make out of this?
Maybe, the reporter was ill informed by priests who continue to spread lies about this illegal rite.
Or probably, the reporter is into it also.
What we know is that the Davao Catholic Herald published a wrong information.
As for Liturgical Rebels...
