Fake News Fact Check: Archbishop Vigano didn't say "Francis’ Religious Indifference is Heretical" The article writer mysteriously forgot to link the LifeSite News article What the Archbishop actually said was: :

“This concept of religious freedom – which replaces the freedom of the one Religion, the ‘freedom of the Catholic Religion to exercise its mission’ and the ‘freedom of the faithful to adhere to the Catholic Church without impediment from the State’ with the license to adhere to any creed, regardless of its credibility and credenda (what we have to believe) – is heretical and irreconcilable with the immutable doctrine of the Church.”

Notice the word "Francis" doesn't appear anywhere within Archbishop Vigano's criticism of religious freedom.

Pope John Paul II…judges Francis’ idea on ‘diversified unity’
Dialogue that only promotes peace, justice, freedom and brotherhood has a negative aspect: it is silent about Christ

Nowadays the kingdom is much spoken of, but not always in a way consonant with the thinking of the Church […] The Church’s task is described as though it had to proceed in two directions: on the one hand promoting such ‘values of the kingdom’ as peace, justice, freedom, brotherhood, etc., while on the other hand fostering dialogue between peoples, cultures and religions, so that through a mutual enrichment they might help the world to be renewed and to journey ever closer toward the kingdom. Together with positive aspects, these conceptions often reveal negative aspects as well. First, they are silent about Christ… (John Paul II. Encyclical Redemptionis missio, no. 17, December 7, 1990)
Over and above unity in love, what is always urgent for us is unity in truth – purity of doctrine is the basis for building up the Christian community

To be watchful for purity of doctrine, the basis in building up the Christian community, is therefore, together with the proclamation of the Gospel, the primary and irreplaceable duty of the Pastor, of the Teacher of the faith. How often Saint Paul emphasized this, convinced as he was of the seriousness of the accomplishment of this duty (cf. 1 Tim 1:3-7; 18–20; 4:11, 16; 2 Tim 1:4–14). Over and above unity in love, unity in truth is always urgent for us. (John Paul II. Address for the inauguration of the Third General Conference of the Latin American Episcopate in Puebla, I, no. 1, January 28, 1979)
Give priority to preventing the tendency to make diverse religions and the various spiritual experiences equivalent

You know well that the basis of the spread of the sects is often a great lack of religious formation, consequently leading to uncertainty about the need to believe in Christ and to belong to the Church he has established. The tendency is to reduce religions and the various spiritual experiences to a least common denominator that makes them practically equivalent, with the result that everyone would be free to follow any of the various paths proposed to reach the goal of salvation. If, in addition, one adds the brazen proselytism which is the hallmark of certain particularly active and invasive groups of these sects, one understands right away how urgently necessary it is today to support the faith of Christians, and to give them an opportunity for ongoing religious formation to deepen their personal relationship with Christ. Your endeavours must give priority to preventing this danger, consolidating in the faithful the practice of the Christian life and fostering the growth of a truly fraternal spirit in the heart of each of your ecclesial communities.

The unity willed by God can be attained only by the adherence of all to the content of revealed faith in its entirety

The unity willed by God can be attained only by the adherence of all to the content of revealed faith in its entirety. In matters of faith, compromise is in contradiction with God who is Truth. In the Body of Christ, ‘the way, and the truth, and the life’ (Jn 14:6), who could consider legitimate a reconciliation brought about at the expense of the truth? […] A ‘being together’ which betrayed the truth would thus be opposed both to the nature of God who offers his communion and to the need for truth found in the depths of every human heart. (John Paul II. Encyclical Ut unum sint, no. 18, May 25, 1995)
The Christian faith is a conscious and free response of man to God’s self-revelation

According to the doctrine contained in the Constitution Dei Verbum, the Christian faith is a conscious and free response of man to God’s self-revelation, which reached its fullness in Jesus Christ. By what Paul calls ‘the obedience of faith’ (cf. Rom 16:26; 1. 5, 2Cor 10: 5–6) the entire man abandons himself to God, accepting as truth what is contained in the word of divine Revelation. (John Paul II. General Audience, no. 1, June 19, 1985)
Conversion to Christ is joined to Baptism not only because of the Church’s practice but also by the will of Christ himself – cooperation that does not lead to Baptism is futile

Conversion to Christ moreover is joined to Baptism not only because of the Church’s practice, but also by the will of Christ himself, who sent the Apostles to make disciples of all nations and to baptize them (cf. Mt 28:19). Conversion is also joined to Baptism because of the intrinsic need to receive the fullness of new life in Christ. As Jesus says to Nicodemus: ‘Truly, truly, I say to you, unless one is born of water and the Spirit, he cannot enter the Kingdom of God?’ (Jn 3:5). (John Paul II. Apostolic exhortation Ecclesia in Africa, no. 73, September 14, 1995)
Among the many dissonant voices the Bishop has the serious responsibility to make things clear

Today especially, among the many dissonant voices that spread confusion and doubt in the minds of the faithful, the Bishop has the serious responsibility to make things clear. The preaching of the Gospel is the greatest act of love for man, his freedom and his thirst for happiness. (John Paul II. Address to the Jubilee of Bishops, no. 5, October 7, 2000)
The successors of the Apostles should never be afraid of proclaiming the full truth about Jesus Christ

Yours is the responsibility of constantly identifying the features of a pastoral plan adapted to the needs and aspirations of God’s people, a plan which will enable all to hear ever more clearly the Good News of Christ and bring the truths and values of the Gospel to bear ever more incisively on the family, on culture, on society itself. The successors of the Apostles should never be afraid of proclaiming the full truth about Jesus Christ, in all its challenging reality and demands, since the truth has an intrinsic power to draw the human heart to all that is good, noble and beautiful. (John Paul II. Address to the Korean Episcopal Conference, no. 2, March 24, 2001)
There is also an urgent need to illustrate and explain more fully the truth that Christ is the one Mediator between God and man

Another plan for a continent-wide Synod will concern Asia, where the issue of the encounter of Christianity with ancient local cultures and religions is a pressing one. This is a great challenge for evangelization, since religious systems such as Buddhism or Hinduism have a clearly soteriological character. There is also an urgent need for a Synod on the occasion of the Great Jubilee in order to illustrate and explain more fully the truth that Christ is the one Mediator between God and man and the sole Redeemer of the world, to be clearly distinguished from the founders of other great religions.
