When you're Pectoral Cross falls into a 'hiding place' accidentally...at the exact moment when you are in an 'interfaith' setting. This is an embarrassment that many Bishops can attest to.
It clearly took His Holiness a long time to realise that his Pectoral Cross had accidentally been hidden.
Why did nobody point it out to the Holy Father?
Why does it always happen at just the wrong moment! Thankfully, we can rest assured that this was not a 'gesture', authentic or otherwise, and that these things just happen, because it seems obvious to me that any Bishop who hides Christ meeting anyone is some kind of, well, I am not sure quite what!
The mysterious disapperance of the Cross was also a phenomenom that affected others in attendance.
Ah well, there's always next time, Your Holiness. An unplanned gesture that could happen to anyone, or, even, everyone! Quick, put your Crosses away lads, its only polite!
The Father of Zionism
Apparently Theodore Herzl, the 'Father of Zionism' - though I am quite sure the true 'daddy' is the Rothschild dynasty - wrote the following in his treatise calling for an establishment of a Jewish State - one gesture that was certainly planned. More can be read about this here. Sounds like a lovely guy. I can't see why St Pius X refused his requests...what was he thinking?
You can be all things to all men, but you can't please everyone. So important therefore, that Our Lord gets a 'look in'. Then, at least you know you've done your best to please one Person!
