I don’t see any reason why we can’t get both.
Good point… maybe.
If you’re saying “why can’t we have a Mass that gives us the Body and Blood of Christ, and other gatherings that are fun and provide entertainment?”, then I’m all with you! Mass is Mass, and a rock band and an uplifting lecture on Scripture are forms of entertainment and learning. Go to each of them, at their own time, in their own context. Make Mass your Sunday morning activity, and a prayer service / concert your Sunday afternoon activity, and let Bible study be your Tuesday evening activity.
If, on the other hand, you’re saying, “why can’t Mass be fun?”, then I’d say I disagree (in principle). Mass isn’t entertainment, in which we’re meant to be spectators. It’s meant to be the worship of God, in which we – as priests in the Kingdom of Heaven – re-present the sacrifice of Christ to the Father. It’s not a spectator sport – it’s supposed to be a “full, active participation” in the representation of the sacrifice!
Should Mass have hymns that are played well and sung beautifully? Absolutely! (Are we donating enough to not only keep the lights on, but also to pay for skilled singers and musicians and their instruments?)
Should Mass have homilies that are uplifting? Definitely! (But, priests aren’t “hired” or fired based on how well they deliver a public speech. Instead, we believe they’re
chosen for a life-long vocation. And, as St Paul reminds us, not all have the same gifts. So, some priests will be great at the pulpit, and others will be great at counseling, administration, teaching, etc, etc.) So, it’s difficult to expect that a priest be required to have the skill set of someone who is hired primarily and
specifically for their ability to deliver a message in a public forum.
