When I was stationed at the Cathedral from 1985 to 1991 as the associate pastor, as we were called back then, rather than parochial vicar, I was not in favor of the return of the Latin Mass or even having some of the Mass in Latin. Bishop Lessard encouraged me to make sure we used the Jubilatio Deo Mass parts in Latin at the Cathedral's 10 AM Mass which featured the men's choir.
I told him no one sings it and we have so many tourists at Mass that they are perplexed too.
In addition to that, Bishop Lessard consulted with the chancery staff at the time, of which I was a part as Diocesan Director of Liturgy, if we should implement Pope John Paul's liberalization of the use of the Tridentine Mass. I was opposed to it. I said, why don't we just do the "new" Mass in Latin and ad orientem, wouldn't that be enough????
Flash forward to 2007 and I am all in favor of the EF Mass being celebrated has Pope Benedict indicated in Summorum Pontificum.
Flash forward to 2016 and I start celebrating the Cathedral's EF Mass once a month on a rotating basis.
Flash forward to December 8, 2019 and I am the priest-celebrant of the Solemn Form of the EF Mass with deacon and subdeaon and using the Cathedral's high altar for it, which hasn't been used for Mass in about 50 years or so.
The high altar, unfortunately, has become a flower and decoration pedestal and reredos for the new altar which is beautifully crafted and is exactly the same design and facade of the old high altar.
I will remember all those Cathedral bishops and priests who celebrated Mass at this high altar since the late 1800's. Eternal rest grant unto them O Lord. Requiem eternam.
