Unitatis redintegratio # 3:

"Moreover some, and even most, of the significant elements and endowments which together go to build up and give life to the Church itself, can exist outside the visible boundaries of the Catholic Church: the written word of God; the life of grace; faith, hope and charity, with the other interior gifts of the Holy Spirit, and visible elements too."

Are the above mentioned incompatible with these pre-conciliar teachings?

Pope Clement VI, Super quibusdam, Sept. 20, 1351:

"We ask: In the first place, whether you and the Church of the Armenians which is obedient to you, believe that all those who in baptism have received the same Catholic faith, and afterwards have withdrawn and will withdraw in the future from the communion of THIS SAME ROMAN CHURCH, WHICH ONE ALONE IS CATHOLIC, are schismatic and heretical, if they remain obstinately separated from the faith of this Roman Church."

 

Pope Leo XIII, Satis Cognitum (# 9), June 29, 1896:

"The practice of the Church has always been the same, as is shown by the unanimous teaching of the Fathers, who were wont to hold as outside Catholic communion, AND ALIEN TO THE CHURCH, WHOEVER WOULD RECEDE IN THE LEAST DEGREE FROM ANY POINT OF DOCTRINE PROPOSED BY HER AUTHORITATIVE MAGISTERIUM."

Pope Boniface VIII, Unam Sanctam, Nov. 18, 1302:

"With Faith urging us we are forced to believe and to hold the one, holy, Catholic Church and that, apostolic, and we firmly believe and simply confess this Church outside of which there is no salvation nor remission of sin, the Spouse in the Canticle proclaiming: 'One is my dove, my perfect one."

Pope Leo XIII, Satis Cognitum (# 9), June 29, 1896: "The Church alone offers to the human race that religion - that state of absolute perfection - which He wished, as it were, to be incorporated in it.  And it alone supplies those means of salvation which accord with the ordinary counsels of Providence."

 

Pope Pius X, Editae saepe (# 29), May 26, 1910: "The Church alone possesses together with her magisterium the power of governing and sanctifying human society.  Through her ministers and servants (each in his own station and office), she confers on mankind suitable and necessary means of salvation."

 

Pope Eugene IV, Council of Florence, "Cantate Domino," 1441, ex cathedra:

"The Holy Roman Church firmly believes, professes and preaches that all those who are outside the Catholic Church, not only pagans but also Jєωs or heretics and schismatics, cannot share in eternal life and will go into the everlasting fire which was prepared for the devil and his angels, unless they are joined to the Church before the end of their lives ..."

"Moreover some, and even most, of the significant elements and endowments which together go to build up and give life to the Church itself, can exist outside the visible boundaries of the Catholic Church: the written word of God; the life of grace; faith, hope and charity, with the other interior gifts of the Holy Spirit, and visible elements too."

Absolutely irreconcilable to Unam Sanctam & Cantate Domino.

Important note:

If one accepts BOD & BOB and rejects EENS in the “Feeneyite” interpretation, it would be possible to reconcile the above teachings.

"Moreover some, and even most of the significant elements and endowments which together go to build up and give life t the Church itself cannot exist outside the visible boundaries: the bible cannot exist outside of the visible boundaries of the Catholic Church, nether can the life of grace, faith, hope and charity, of the gifts of the Holy Ghost."

Can the life of grace, faith, hope and charity, exist outside the visible boundaries of the Catholic Church?  Of course it can.    In fact, the proposition that " Outside of the Church, no grace is granted" (Denz 1379) is condemned.

Baptism administered outside the visible boundaries of the Catholics Church, provided the correct form is used) is valid. Therefore, those who receive baptism outside of the visible boundaries of the Catholic Church (certainly children below the age of discretion), receive grace, faith, hope and charity, through the sacrament.

bzzzzt.  That Denzinger quote is speaking of actual grace, not sanctifying grace, i.e. "life of grace, faith, hope and charity".  You should know better than this.

Those such as infants who receive the Sacrament of Baptism instrumentally by the hand of non-Catholics are in fact members of the Catholic Church.  You can have an atheist validly baptize, but the conferral of the effect of the Sacrament is solely upon those within the Church.  So the LIFE of grace that results from the Sacrament is in a subject who is inside the Catholic Church.  There can be instrumental causes of grace coming from sources that are outside the Church, but the life of grace can only exist in those who are inside the Church, and to declare otherwise is in direct contradiction of Catholic EENS dogma.  So the "visible" elements part I'll grant, according to this scenario, but not the sanctifying grace that comes with it.
