They have been ruled theologically incorrect and of human origin.
The offical statement from the diocese and ordered to be attached to any of his writings as of July 7, 2000:
Bishop Matthew H. Clark, Bishop of Rochester, has accepted the unanimous judgment of a special mixed Commission set up to study the writings of John Leary.
After reading the volumes and meeting with Mr. Leary, they testified that they found him psychologically sound and spiritually serious.
They concluded that his locutions are not a fraud perpetrated on the Catholic community. Nevertheless, in their judgment, his locutions are of human origin, the normal workings of the mind in the process of mental prayer.
Of grave concern to the Bishop and the Commission, however, are the errors that have found their way into his writings, two of which are most serious.
The first is called by the Chruch "millenarianism". This erroneous teaching, contained in the first 6 volumes of Prepare for the Great Tribulation and the Era of Peace, holds that Christ will return to reign on the earth for a thousand years at the end of time. As the catechism of the Catholic Church expresses it:
"The Antichrit's deception already begins to take shape in the world every time the claim is made to realize within history that messianic hope which can only be realized beyond history through the eschatological judgment. The Church has rejected even modified forms of this falsification of the kingdom to come under the name millenarianism..." (CCC #676)
The second error is "anti-papalism". While the Church holds that the Pope "by reason of his office as Vicar of Christ, namely, as pastor of the entire Church, has full, supreme and universal power over the whole Church"
(Vatican II, Constitution on the Church, #22),
Mr. Leary's locutions select Pope John Paul II to be obeyed but his sucessor to be ignored as an "imposter pope". This erroneous teaching is found in all the volumes.
Because Mr. Leary has reaffirmed the teaching and discipline of the Church and acknowledged the teaching authority of John Paul II and Bishop Matthew H. Clark and their sucessors, Bishop Clark has permitted these volumes to be published with this warning to its readers appended.
