One of my favorite Mary Days is the feast of Our Lady of the Pillar. This Mary Day honors the time when Mary - who was still alive - bilocated to Zaragoza Spain, and appeared to St. James the Greater. James purportedly traveled to Spain/Hispania after Pentecost to preach about Christ. After some time of adversity, Mary visited James - resting upon a pillar - and offered the apostle encouragement and prayers. With this dose of spiritual renewal, James was able to continue his mission, greatly impacting the faith of the Spanish people.
Feast Day: October 12
