From YouTube: History of over 250 Incorruptible Catholic Saints
The following information regarding the incorrupt bodies of saints can be read on CatholicApologetics.com:
The incorrupt bodies of these saints are simply a living witness or proof to the truth of the Catholic religion as the one true faith from God, who has confirmed the testimony of the Church in the great miracles he has worked through it's saints.
The Council of Trent:
"The bodies of holy martyrs and others now living with Christ, bodies which were His members and temples of the Holy Spirit, which one day are to be raised up by Him and made glorious in everlasting life, are to be venerated by the faithful; God gives men many benefits through them."
The Bodies of the saints for us are like great and holy relics, which move us to honor the saints who God has chosen to honor by preserving them incorrupt.
In scripture we read that the use of the bones of Elisha brought a dead man to life: "So Elisha died, and they buried him. Now bands of Moabites used to invade the land in the spring of the year. And as a man was being buried, lo, a marauding band was seen and the man was cast into the grave of Elisha; and as soon as the man touched the bones of Elisha, he revived, and stood on his feet." (2 Kgs. 13:20-21).
A woman was cured of a hemorrhage by touching the hem of Christ's cloak (Matt. 9:20-22). The sick were healed when Peter's shadow passed over them (Acts 5:15-16). "And God did extraordinary miracles by the hands of Paul, so that handkerchiefs or aprons were carried away from his body to the sick, and diseases left them and the evil spirits came out of them" (Acts 19:11-12).
The Power of the relics to work miracles doesn't come from the object itself but from God, who confirms the faith of the person who is healed by means of them as to testify to the holiness of His saints.
