Telekinesis, which means a displacement of an object through space under non-natural causes, was possibly observed during the Fall season of 2009. This event occurred during communion at the SSPX's church of Veneta, Oregon (USA).
For the sake of discretion, I'll name the principal witness "Traveler". Traveler is a militant of the Church. He holds a Commercial Pilot's License. He may be identifiable to who-ever wishes to pursue the matter by a publicly known occurrence: a night forced-landing (1994) at the commands of his private aircraft in the desert part of Northern California after having overflown both the Malheur Lake, Oregon and the Black Rock Desert, Nevada while on a trip started from Spokane, Washington. This night forced-landing scrambled the Search & Rescue. Traveler may be considered a reliable witness for he is both a faithful, and, being a pilot, a prime observer of matters concerning "telekinesis".
The Mass was said by Father Cooper, SSPX. Father Cooper is of the kind of childish innocent believer. His homilies may sound infantile to the hard-of-heart. He is without a doubt one among the faithful who makes the delight of God, and there is no doubt that Jesus Christ Our Lord, under the watchful eyes of our most beloved Mother the Blessed Virgin Mary, descent from heaven into his blessed hands during the Transubstantiation. Father Cooper's Masses are most certainly valid, which naturally makes them subject to demonic attacks.
Father Cooper's homilies for example speaks warmly of Saint Mary-Magdalene, who "must be now very close to God up in heaven", or again he showed great enthusiasm when "the nuns are coming!" (that was the time when a group of nuns of the SSPX moved in the Priory of Veneta from New York State), or again (that was 2009) "the restoration of the tradition in Rome is coming", etc. It is thought that Father Cooper is saintly, although somewhat naive to the vicissitudes of the world. He, therefore, is a prime target to the devil.
During communion, Traveler went on his knees at the communion-rail. He was at the far left side (facing the Altar). This location at the communion-rail was therefore on the left side of a wide column separating from the central section. A middle aged woman, with her head covered and wearing a traditional dress of pale-blue color was kneeling by the right side of Traveler between him and the column. Father Cooper, and the altar-boy appeared, and this is when the event occurred. The priest put his hand in the ciborum. A host became visible from between his thumb, and index finger. The host then disappeared from his fingers, as if seeming to have dropped back into the ciborium. This is what seemed to have occurred because the priest had no abrupt movement of his hand. The priest seemed to have a moment of hesitation. He looked down on the floor, then on the Paten. Traveler also looked down on the floor and also on the Paten. No fallen host was in sight. Father Cooper appeared concerned, and then after a few seconds resumed the distribution of the Holy Eucharist, by saying Corpus Domini nostri Jesu Christi custodiat animam tuam in vitam eternam. Amen to both the middle-aged lady, and to Traveler.
After Mass, Traveler observed Father Cooper with acolytes, searching for something around the communion-rail. It was obviously something of great value that they were searching, because poor Father Cooper was on his four. After several minutes of intense search, a faithful pointed at what was looked-for. It was a host. The priest took it and cleaned the floor with a white piece of cloth and holy water. A host had escaped from the priest's fingers, and this is what Traveler witnessed.
It was without a doubt a preternatural act from the devil, because the host was found SEVERAL FEET AWAY AT THE CENTRAL SECTION OF THE COMMUNION-RAIL and BEHIND THE COLUMN THAT SEPARATED FROM WHERE THE HOST HAD ESCAPED TO WHERE IT WAS FOUND. There was no possible straight line between the escape of the host, and its drop-point on the floor, and in addition, there was no "tossing" nor "launching" movement from the hand or fingers of the priest.
This report is verbatim to the event. The celebrant, as well as the acolytes, and a few faithful of Veneta probably remember it.
