Apostolic Letter of Pope Pius IX
Iam Vos Omnes (1868)
Apostolic Letter of His Holiness Pope Pius IX to all Protestants and other Non-Catholics at the convocation of the [First] Vatican Council, Sept. 13, 1868, that they might return to the Catholic Church
TO ALL PROTESTANTS AND OTHER NON-CATHOLICS
Pius IX, Pope
You all know already that We, having been raised, notwithstanding Our unworthiness, to this Chair of Peter, and therefore invested with the supreme government and guardianship of the whole Catholic Church, divinely entrusted to Us by Christ our Lord, have judged it seasonable to call to Us Our Venerable Brethren, the Bishops of the whole earth, and to unite them together, to celebrate, next year, an Ecumenical Council; so that, in concert with these Our Venerable Brethren who are called to share in Our cares, We may take those steps which may be most opportune and necessary, both to disperse the darkness of the many noxious errors which everywhere increasingly prevail, to the great loss of souls ; and also to establish and confirm daily more and more among the Christian people entrusted to Our watchfulness the Kingdom of true Faith, Justice, and the Peace of God.
