Feast Day of St. Louis Mary De Montfort .

He made waves with many things, including this statement, albeit I've yet to see it in the original French:

"All Christians have but one Faith and adore one and the same God, all hoping for the same happiness in heaven.

"They have one Mediator Who is Jesus Christ and therefore they must all imitate their divine Model and in order to do this they must meditate on the mysteries of HIs life, His virtues and of His Glory."

He most likely wrote this in around 1700 AD. This quote is froin page 60 of his The Secret of the Rosary.
