If you read the entire thread you would see that what I mean by accidentally commit a mortal sin as opposed to one on purpose I am talking about situations where the person did not intend to commit one but did anyway. There is probably a better term for what i mean but I don’t know it. I was talking about trying to differentiate between when a person is in a state of mortal sin and an EMHC and shouldn’t be in the role (i.e adulterer, worker in abortion mill, etc.) or doing it at the time but had plenty of time to make it right (i.e. refrained from going to confession) and the person that has the role of EMHC and between being assigned the position and getting to the person they are taking the Eucharist too commits a mortal sin through no fault of their own other then being human.
Perfect example would be if the EMHC was on the way from the church to the person/hosptial and gets in a car accident, in the heat of anger commits a mortal sin. If that same person goes on and give the Eucharist to the sick person they are in no way invalidating what they receive.
Another example, EMHC is assigned to goto the hospital on Sunday. Saturday night commits a mortal sin, EMHC is unable to transfer position to anyone else and goto confession because priests are busy and will not hear their confession. EMHC can still take the Eucharist to the hospital. Since their is no requirement to receive the Eucharist before distributing it outside of Mass they still can take it.
As I said before an EMHC should not be in the state of sin when taking communion to the sick. They should make every effort not to be. No matter what it does not invalidate the sacrament. And if they made every effort to make the situation better and couldn’t they are probably not committing a sin. Like I also said this is a matter between the EMHC, the pastor and/or their confessor.
