Another practice I have seen is the anointing of "prayer cloths" and then sending them to those who are ill or in need of a healing. I have read this in the Bible, but never attended a church who participated in this practice until a few years ago.
Always in His care,
I do believe it is a Biblical practice, and have seen it done in church. What I would have problems with are churches that sell anointed prayer clothes. I have seen that shameful practice done too.
