I would be remiss to let the feast day of Elisha (Eliseus) the Holy Prophet come and go (it was actually two days ago) without pointing out (yet again) that he provides for us in the Scriptures a most clear example of the power of God through the relics of Saints. The Greek Orthodox reading for his feast day points out:

But even after his death God glorified him; for after the passage of a year, when some Israelites were carrying a dead man for burial and suddenly saw a band of Moabites, they cast the dead man on the grave of the Prophet. No sooner had the dead man touched the Prophet’s bones, than he came to life and stood on his feet (IV Kings 13:20-21). Mentioning this, Jesus the Son of Sirach says, “He did wonders in his life, and at his death his works were marvelous” (Ecclus. 48:14). It is because of such marvels that the faithful have reverence for the relics of the Saints (see also Jan. 16).

We also see in the Acts of the Apostles the examples of healing through the “handkerchief” of St Paul and the very shadow cast by St Peter.

For those feeling squeamish about the idea of relics and their miraculous ability to heal people from illness, etc., look no further than the Scriptures themselves for justification. Any “tradition” that would balk at relics and their veneration is not a tradition of the Holy Spirit as found in the venerable Scriptures; it is a tradition of men.
