The authority for healing is not of hankerchiefs or aprons or in whoever owned them - the authority is from God. Remember you worship a jealous God and by placing your faith in relics or by bowing in front of a graven image or by using any intermediary between yourself and God other than the Lord Jesus you go against His commands.
Exodus 20:3
3 "You shall have no other gods before me.
4 "You shall not make for yourself an idol in the form of anything in heaven above or on the earth beneath or in the waters below. 5 You shall not bow down to them or worship them; for I, the LORD your God, am a jealous God, punishing the children for the sin of the fathers to the third and fourth generation of those who hate me, 6 but showing love to a thousand {generations} of those who love me and keep my commandments.
Matthew 4:8-10
8Again, the devil took him to a very high mountain and showed him all the kingdoms of the world and their splendor. 9"All this I will give you," he said, "if you will bow down and worship me."
10Jesus said to him, "Away from me, Satan! For it is written: 'Worship the Lord your God, and serve him only."
