Lenten ping.
No. Not even La Salette
And St. Catherine Laboure's apparation of Mary that gave us the Miraculous Medal was most certainly approved as well.
There is also approval of the apparations at Beauraing
Although there were problems from some quarters opposition to Beauraing had practically ceased by the time the bishop appointed a commission of inquiry in 1935, with the work continuing under his successor. In February 1943 Bishop Charue authorised public devotions to Mary at Beauraing, but it was not until July 1949, following the Second World War, that the shrine was officially recognised and two important documents issued. The first dealt with two of the many cures that had taken place at Beauraing, declaring them to be miraculous.
The second document was a letter to the clergy in which the bishop said, "we are able in all serenity and prudence to affirm that the Queen of Heaven appeared to the children of Beauraing during the winter of 1932-1933, especially to show us in her maternal Heart the anxious appeal for prayer and the promise of her powerful mediation for the conversion of sinners."
Banneaux also received approval:
Banneux was investigated from 1935 until 1937 by an Episcopal commission, after which the evidence collected was submitted to Rome. Meanwhile growing numbers of pilgrims came to the shrine, and in May 1942 Bishop Kerkhofs of Liege approved the cult of the Virgin of the Poor. In 1947 the apparitions themselves received preliminary approval, with this becoming definite in 1949. Like the children at Beauraing, Mariette married and had a family, being, like them, content to remain in the background.
