I think it is beautiful to see people so obviously engaged in worshipping our Lord, praying and singing their hearts out. Some people may not be familiar with a charismatic-style worship and that may make them uncomfortable, but actually there is no suggestion of tongues or prophecy, etc. here, just people raising their hands to the Lord, which is a very ancient prayer posture, and one that is mentioned frequently in the psalms and not an attempt to imitate the priest, and not necessarily “charismatic”. It appears there is a Litany being sung, which is very beautiful.
There is nothing going on here which is improper or forbidden by the Church. This is not a Mass, it is Eucharistic Exposition and Adoration. People sing and pray during these services all the time, in various ways. I have been to similar services and found them to be very powerful and beautiful with a strong sense of the Presence of the Lord. After all, where 2 or 3 are gathered, He is there.
And one other thing–Protestants do not expose the Blessed Sacrament and worship Christ in the Eucharist in this manner. That fact alone ought to dispel any idea this is a “Protestant-looking” service. Even in charismatic Protestant churches you do not have an altar with the Blessed Sacrament exposed and people on their knees adoring it and priests in vestments and candles and incense and all that gold–why would anyone think it looked like a Protestant service? That is just an excuse for a complaint about something which is unfamiliar. Anyone can plainly see this is not a Protestant prayer meeting. And a large group of Catholics gathering together to praise the Lord out loud and in a joyful manner out to be a cause for rejoicing, not criticism.
