In 2019, news came out of Seattle of Robert Fuller who died via assisted suicide. Two reports about how his parish dealt with it also emerged. I will quote both reports. His story raises questions about how we as a Church should help people intent on assisted suicide or euthanasia. After the news stories, I will explain Church teaching.

"he considerd himself a shaman". Novus Ordo laity at their finest and it gets worse: the whole parish is fail. He "read scriptures from the lectern, sometimes delivering insightful or funny remarks off the cuff". Reading Scripture during the liturgy is a job for clergy. Delivering a commentary on Scripture is also a job for clergy and doesn't happen during the readings. No matter what the pastor …More

No matter what the pastor supposedly did or didn't "know" of this "shaman's" intentions, it's clear he's been letting his parish turn into a circus with this clown being the ring-master right down to the "elaborately carved walking stick".

Was it mentioned that he "married" his homosexual partner before he killed himself?

Good analysis and instruction on your part, Father. As far as the diocesan guidelines are concerned, the allowance for absolution in the case of someone who is merely open to changing their mind seems quite wrong, to me.

Good analysis and instruction on your part, Father.

One needs true contrition, even if it only is due to a fear of eternal damnation. The “beginning of contrition” is a good thing, I suppose, but is inadequate matter for absolution. Also, my understanding of assisted suicide laws is that they require that a person be of sound mind, able to make the choice to kill themselves, without duress. This would seem to make mortal sin public, and official.
