"...the women with the stones/crystals actively approach people and offer their healing practice...... they have access to all the wards.
I did not realize this. In my opinion this is not acceptable. I assure you, most hospitals *I* am aware of do not allow such things.

Then you say:
"...as a Christian I see it as my duty to offer prayer for ANYONE in any situation who I think might need it."

followed by:

".. miracles are performed by God when Christians pray for others who do not necessarily believe in the power of prayer or in Gods existence even. The person receiving the healing does not have to believe."

The last one seems to not require the other. I would think that IF prayer is efficacious, it would not need to be offered to possibly uninterested persons. Thus, the nurse could have silently done what she...and you... consider your Christian duties, without upsetting anyone! Then...*IF* a patient indicates their desire to share a prayer session with someone they like & trust, that can easily be arranged, whether a stone/crystal bearer or a religious person of their choosing.

In hospitals I am familar with, there are standard, easily accessed ways to obtain spiritual help and prayer...and I have NO objection to this. The information usually entered in a patient's chart when they are admitted.
