Bishop Williamson still believes in Garabandal.
How about this though.... with Garabandal you need to see that there is a hierarchy in the level of certainty in the apparitions/ phenomena.
The last chapter of She went in haste to the mountain also talk of this
1) most worthy of belief are the visible day to day reality of the long ecstasies, the children praying in the cold in the winter for many hours, the spontaneous response the the llamadas, the ecstatic marches, the knowledge of holy things given to the children and of priests who were under cover... the many phenomena such as these that were seen by thousands of witnessess and are clearly supernatural or (preternatural)
2) the first public message that was given in apparition all the children agreed on and understood as from Our Lady
3) any messages from the apparitions that all the children saw/heard have individually reported
4) the 2nd message that was given publically but only to concita, but which the others attended and understood to be genuine and in accord with the many private conversations they had with our lady
5) so called bits of speech reported to be from conversations between the children and the Virgin
6) locutions that the children individually reported to have received interiorly and where only one child received the message
for me the whole Joey thing is on level 6. I believe in Garabandal solidly on level 1)
I believe it less solidly down to level 4
level 5 and 6, nah. I don't think so, there is too much room for human error there and the messings of human psychology.
So, in conclusion, when one accepts Garabandal as a place our lady appears that is one thing, but it need not require you to thereby accept so called locutions supposedly heard by the grown up children some time later.
This kind of analysis one could even do with Fatima, e.g lower down the level would be the so called sayings of Jacinta to mother Godhino, In this case, let me add, I accept all of them, but point remains one can accept things around an apparition to one degree or to another.
In Christ and with the Immaculata, Refuge of Sinners.
