EXCLUSIVE: Catholic composer accused of sexual battery worked with known predator for years

Over the weekend, Catholic hymn composer, performer, and youth conference organizer David Haas was dropped by his publisher after the company learned the musician was under investigation by the Archdiocese of St. Paul and Minneapolis for sexual battery and other offenses.

Haas also ran a music camp for teens called Music Ministry Alive, which according to Haas’ website, is “an international liturgical music formation effort for high school and college age youth.” (Both the Facebook group and the official website for Music Ministry Alive have been removed).

For followers of this blog, Music Ministry Alive (MMA) should ring a bell—and it got my attention immediately when reading about Haas.

Back in 2012, I wrote about how MMA was the music home of credibly accused former Hilo priest George De Costa. I even went to his former parish in Hilo, to talk to Catholics about the lawsuits. Locals knew that DeCosta was a predator, but the former cleric was running his own, non-church affiliated retreat center at the time. Outside of warning people and spreading the news about the lawsuits, there was little else that could be done.

By 2016, DeCosta had been sued for child sexual abuse by at least nine men.

But that didn’t stop Haas and MMA from working closely with DeCosta and singing his praises.

In a 2017 essay—reprinted in his 2018 book—Haas describes his yearly trips to Hilo to visit DeCosta and participate in the Big Island Liturgy and Arts Conference.

He says:

I love my annual visits to Hawaii, as each one calls to mind that first conference experience, this song, and the deepening of such important friendships. The song is dedicated to Fr. George; his passionate preaching, teaching, and witness of ministry is like the fire of the volcano—always stirring, never tiring, always convicted. I love every opportunity I have to be there. When I am not able to do so, I have to resort to watching the episodes of “Hawaii-Five-O” to keep me connected. Mahalo! (11.22.17)

From Haas’ website

This is YEARS after DeCosta was the subject of at least nine sex abuse lawsuits.

MMA and Haas knew in 2012 about the allegations against DeCosta and the fact that he was removed from the priesthood. How do I know this? I TOLD THEM.

I wrote MMA a letter informing them of allegations and lawsuits, as well as asking that MMA officials inform all past participants and that DeCosta be banned from all future events.

Obviously, they didn’t listen and didn’t care.

What does this tell us?

The multiple allegations against Haas should surprise no one. In fact, I anticipate that as the “investigation” against Haas continues, we will learn that the women he preyed on were silenced for years. Why should Haas treat himself any differently than he treated De Costa?

This is a story that is all too familiar.

Haas traveled extensively, performing and “mentoring” adults and youth. The following list was taken from his website.

  1. According to the post, referred to on the NCR article, his former wife (divorced for 25 years) Jeanne Cotter claims as part of the annulment friends and colleagues wrote letters acknowledging his sexual infidelity and even sex addiction experts knew. He retaliated against her by canceling joint booked dates and recontracting them as his events only or his events with another female.
    After reading the whole article it appears he would get angry with any female who scoffed his advances and these were 16-18 young women who attended his workshops and MMA.

    Doesn’t sound like the kind of guy young women or anyone involved in getting paid with him would want to take on.

  2. As a professional musician also employed by a Catholic church I have often wondered why he seemed to have such a “hold” on so many within parish music circles. His music isn’t that great nor half the time appropriate for a liturgical celebration, and I often thought it was composed to market to a publisher for a quick sell. Yet, so many people seemed mesmerized by him as if he were larger than life. I often observed that after someone attended one of his “workshops.” Can you say, “brainwashing?”
