There are those who believe that Anointing of the Sick should not be counted as one of the seven sacraments. I would strongly urge such a one to read the gospels. Jesus had such a very strong love of the poor. He spent His entire ministry caring for the sick. What is more, Jesus used water, mud, and even His own spit to cure people’s ailments. Not to mention, the forgiveness of sins usually accompanied the cures.
One should also take a look at James 5. Here see an Apostle recommending the calling of the “presbyters” to pray for the sick, and anoint them with oil. So before questioning whether or not this should be numbered among the sacraments, one ought to consider this evidence.
