My own hesitancy about joining the Church is not about its eucharistic theology, but rather around the unwillingness of the Church to commission, ordain and welcome all humans as Jesus did: male and female, married and unmarried, saints and sinners. I believe that the Church, God's people and all of creation have suffered from this omission.
If someone believed Catholic Eucharistic theology and that the Catholic Church is "the Church", then it would seem to follow one would join and stay despite anything. The reasons people do not join or stay in the Church might indicate the actual level of belief in Catholic Eucharistic theology, among other things. Among those other things, where might Haugen have gotten the idea that Church teaching on ordination involves an "omission", as if a To Do list has been misplaced for two millennia? From what I see and hear, probably from some of the Church's clergy and staff.
P.S. I can't claim he is utterly lacking in perspective.
I do not think of my own music as central or important to Roman Catholic worship, present or future.
Sounds like we'd hear less of his music at St. Al's if he was the Director of Liturgy and Music.
P.P.S. At Catholic Wintertime In Milwaukee, a call for more liturgical diversity in the Archdiocese of Milwaukee, such as more Michael Joncas. I understand he once wrote something called "On Eagles Wings".
