The collected remains of the head of John Cassian is at best parts of a skull.
This is what a website records about “Holy bones in Saint-Victor Abbey in Marseilles”.

My comment:
The most interesting part of this story is the bone collection inside the “Church” in Marseilles.
All kinds of pieces of bones are collected and kept in strange looking golden boxes. That this is holy bones, can only be confirmed by the crosses on top of the boxes.
To anyone who still doubts about the Roman Catholic Church being the skull and bones society, take a look at the skull and bone files on this blog.
Lets also learn from Jesus. He spoke about people who he compare to dead bones, unclean people. Today we know that people who collect and adore bones, are not washed in His blood.
Matthew 23:27
“Woe to you, teachers of the law and Pharisees, you hypocrites! You are like whitewashed tombs, which look beautiful on the outside but on the inside are full of the bones of the dead and everything unclean.

The Truth comes to light….even if this is not solely about the Skull & Bones crowd, it sure puts a lot of light on 'where those bones are kept'…No society that goes by any name, will not have a collection
of Pride, to brag and many ideas, and a lot of help to drag the populace into getting more items. This is just way too coincidental ..they make their-selves look good, while another (place to hold and savor their demonic deeds under the guise it's Holy) What better way to drag the blind into more …Sick, sick, sick! You know Jesus told us, all things hidden will come to light. The more I see and hear
the more I see and hear! Those who have eyes to see, and ears to
hear know what I'm saying. Line everything against the Word of God, and test all spirits. They may change their clothes, but they can never change their spots!! Just in our country, each Party will
and does say ''we will change and fix things"..yet they too were in
Power and nothing was changed or fixed…just YOUR CHANGE was put in their pockets and "a NEW FIXED AMOUNT WAS FIXED while the other party screams…foul'…!! Yet many Christians are all
upset each day about how 'things' are going…and getting more and
more blinded either by the lies of the public 'programmers' or by the Pulpit. The Book of Jude is so 'Today' for us all to take heed!
