"The Holy Church encloses relics of the Saints in the altar because from the time of the Catacombs she used to offer the divine Martyr of Golgotha as close as possible to the remains of those who were martyred for Him. In the unbloody Sacrifice of the Mass, all Christians, as members of His Mystical Body, are offered up by Christ and with His physical body to the Holy Trinity. Moreover, they have to continue His Bloody Sacrifice: Jesus has finished suffering in His flesh; but His mystical members in their turn should offer their sufferings to God in union with those of Christ."
You may not understand, nor necessarily appreciate these practices and beliefs, but do recognize why we do and why the Roman Church has practiced these rites for tens of centuries...
7 But we have this treasure in earthen vessels, that the excellency may be of the power of God, and not of us. 8 In all things we suffer tribulation, but are not distressed; we are straitened, but are not destitute; 9 We suffer persecution, but are not forsaken; we are cast down, but we perish not: 10 Always bearing about in our body the mortification of Jesus, that the life also of Jesus may be made manifest in our bodies. 11 For we who live are always delivered unto death for Jesus' sake; that the life also of Jesus may be made manifest in our mortal flesh. 12 So then death worketh in us, but life in you.(2nd Cor. 4)
Do you find this strange, too?
Acts, Chapter 19:
11 ¶ And God wrought special miracles by the hands of Paul:
12 so that from his body were brought unto the sick handkerchiefs or aprons, and the diseases departed from them, and the evil spirits went out of them.

God manifests His power in many ways, and uses material things, including the bodies of His saints, to show forth His Glory and Majesty.
I'm sure God will be tickled pink to hear you find His miracles objectionable. Right on par for the doctrines of man, "I determine truth" group.
