When Jesus healed people we are not always told what if any physical rituals or ceremonies he performed. Often he seems to have just helped someone to their feet and they were healed (Mark 1:29-39). The disciples anointed the sick with oil (Mark 6:13). Jesus, however, did one time anoint a man with mud made from his own spit for his healing and then asked him to wash himself in water (John 9:6-11). We could do that if people prefer, but somehow I think that most will opt for the example of the disciples and the instruction in James 5:14-16 to use oil. Who were the elders that James mentioned? The word elder means many different things to different denominations today. But, in the historical context of the day the word referred to local church leaders.
