There are many problems in the Church due to the confusion among Christians between the Word of God and private revelations. There are many Christians who give much importance to private revelations, almost as if these were the only revelation and the “faith”, without knowing the Word of God, which is the only Word of Faith, and where Faith comes from.
For better clarification we transcribe the no. 14 from the Post Synodal Verbum Domini Exhortation, where Pope Benedict XVI explains to us, in his authority of Shepherd and great theologian:
«In all of this, the Church gives voice to her awareness that with Jesus Christ she stands before the definitive word of God: he is “the first and the last” (Rev 1:17). He has given creation and history their definitive meaning; and hence we are called to live in time and in God’s creation within this eschatological rhythm of the word; “thus the Christian dispensation, since it is the new and definitive covenant, will never pass away; and no new public revelation is to be expected before the glorious manifestation of our Lord Jesus Christ (cf. 1 Tim 6:14 and Tit 2:13)”. Indeed, as the Fathers noted during the Synod, the “uniqueness of Christianity is manifested in the event which is Jesus Christ, the culmination of revelation, the fulfilment of God’s promises and the mediator of the encounter between man and God. He who ‘has made God known’ (Jn 1:18) is the one, definitive word given to mankind”. Saint John of the Cross expresses this truth magnificently: “Since he has given us his Son, his only word (for he possesses no other), he spoke everything at once in this sole word – and he has no more to say… because what he spoke before to the prophets in parts, he has spoken all at once by giving us this All who is his Son. Any person questioning God or desiring some vision or revelation would be guilty not only of foolish behaviour but also of offending him, by not fixing his eyes entirely on Christ and by living with the desire for some other novelty”.
Consequently the Synod pointed to the need to “help the faithful to distinguish the word of God from private revelations" whose role “is not to ‘complete’ Christ’s definitive revelation, but to help live more fully by it in a certain period of history”.
The value of private revelations is essentially different from that of the one public revelation: the latter demands faith; in it God himself speaks to us through human words and the mediation of the living community of the Church. The criterion for judging the truth of a private revelation is its orientation to Christ himself. If it leads us away from him, then it certainly does not come from the Holy Spirit, who guides us more deeply into the Gospel, and not away from it. Private revelation is an aid to this faith, and it demonstrates its credibility precisely because it refers back to the one public revelation.
Ecclesiastical approval of a private revelation essentially means that its message contains nothing contrary to faith and morals; it is licit to make it public and the faithful are authorized to give to it their prudent adhesion. A private revelation can introduce new emphases, give rise to new forms of piety, or deepen older ones. It can have a certain prophetic character (cf. 1 Th 5:19-21) and can be a valuable aid for better understanding and living the Gospel at a certain time; consequently it should not be treated lightly. It is a help which is proffered, but its use is not obligatory. In any event, it must be a matter of nourishing faith, hope and love, which are for everyone the permanent path of salvation.»
