A Photo a Day: My Daily Sustenance, Day 132

In the Catholic faith, the whole month of May is dedicated to the Blessed Mother Mary.  So it is fitting that we celebrate Mother's Day in May.
Below is the explanation about the tradition.  I found it on a site about Catholicism.  


By tradition, the Catholic Church dedicates each month of the year to a certain 
devotion. In May, it is the Blessed Virgin Mary. This devotion arose among Jesuits 
in Rome in the late 18th  century and quickly spread throughout the Western Church. 
By the time of Pope Pius IX's declaration of the dogma of the 
Immaculate Conception in 1854, it had become universal. 
May crownings and other special May events in honor 
of Mary, such as public recitation of the rosary, stem from this time.
