What are you trying to say by this statement? I’m honestly confused.
They are not blessing the patients, according to you, but the staff. Unless I am missing something or you left out a part
It is a UCC facility and UCC allow women ministers, and Protestant ministers do bless other Protestants. If you’re objecting to that, IMO, it’s no different than a Jewish patient in a Catholic nursing home concerned that they have daily Mass.
If you don’t want your husband “exposed” to Protestant practices, you do have the right to have the non-Catholic chaplaincy staff to stay away.
As far as what the Church teaches, it does not to my knowledge, prohibit Catholics and Protestants from praying with each other, or for each other. Since a blessing is usually a request for God’s abundance to poured out on another individual, I don’t see this is a big issue
— but I am sure if I am wrong, I will be severely corrected and castigated on this forum, and my orthodoxy called into question
God bless to you and your husband
