Saints Jacinta and Francisco?

With Canonization comes the obligation, not just the privilege, to render the due justice of universal public veneration to someone whose life, and God's working in that life, has been crowned with the eternal vision of God. Canonization does not put a person in heaven, it recognizes that God's grace and their cooperation with grace has done so.

Between Beatification and Canonization there exists but two obstacles, one procedural and one spiritual. The procedural obstacle is the approval of a second miracle, first through a Process in the diocese in which it occurred, and then by the Congregation for the Causes of the Saints. The spiritual obstacle is the certainty of the Supreme Pontiff that the person is worthy to be canonized. 

Thus, in this way, by practical tests, of the life, of the intercessory power of the candidate, and by the prayerful and serene judgment of the Pontiff, the Holy Spirit works through human instruments to ensure the authenticity of a canonization.

In the words of the formula from the canonization of St. Teresa Benedicta of the Cross (Edith Stein) we can see the solemn judgment and infallible authority of the Supreme Pastor of the Church at work and hope that the day will come when these words will be pronounced on behalf of Jacinta and Francisco.

For the honour of the Blessed Trinity, the exaltation of the Catholic faith and the fostering of the Christian life, by the authority of our Lord Jesus Christ, of the holy Apostles Peter and Paul, and our own, after due deliberation and frequent prayers for the divine assistance, and having sought the counsel of our Brother Bishops, we declare and define that Bl. Teresa Benedicta of the Cross, Edith Stein, is a saint and we enroll her among the saints, decreeing that she is to be venerated in the whole Church as one of the saints. In the name of the Father, and of the Son and of the Holy Spirit.
