James 3:12
Can a fig tree, my brothers, produce olives, or a
grapevine figs? Neither can salt water yield fresh.
The tests of such apparitions of Mary have shown that nothing
in her messages and consequent devotion contradicts the word
of God and the constant teaching of the Church.
 
The fruit of the shrines of Mary speak for themselves:
repentance, revival, healings, renewed faith, return to the
church, Bible reading, fruits of the Spirit, etc. The Church has
made and continues to follow the Biblical tests of the spirits
and approves some such apparitions as of the Spirit.
 
It remains for all Christians of a renewed mind and of the
Spirit of the Lord to follow the Biblical mandates of testing
spirits and the fruit of the tree as the Catholic Church has done.
