Someone once told me if a person is wearing a cross and a medallion, chances are they are Catholic *grin
(This of course after meeting me and seeing my own cross and medallion around my neck)

A friend of mine from church gave me a Miraculous Medal (that is literally what it's called) and I never understood what it meant..
I mean, I knew Catholics carried medals with them of the various saints etc for various reasons, like St Christopher is to help protect travellers, St Anthony is to help people find things...etc.

So I decided to look up online as to what in the world did my medal mean...
And when I looked at it, I realised that it really has indeed touched my life the way its supposed to...(Info from here: http://www.medjugorje-online.com/miraculousmedal.php)

Miraculous Medal

The Blessed Mother appeared to St. Catherine Laboure in Paris and asked her to have this medal struck and distributed.

For the past century, the Miraculous Medal has been the most popular medal of all time.

The apparition happened in 1830. When the Virgin Mary appeared to St. Catherine Laboure, she granted her a vision of the Miraculous Medal, front and back, and she said, "All who wear them will receive great graces."

The back of the Miraculous Medal features an "M" joined with a cross, as well as two hearts which are said to signify the Sacred Heart of Jesus and Immaculate Heart of Mary.

These powerful words frame the front of the pendant: O Mary, conceived without sin, pray for us who have recourse to thee.
