"Today, the Church of Christ is shining with the dual lights..."

Sts. Mary Magdalene the Equal-to-the-Apostles and Markella of Chios the Virgin Martyr (source)

  
Today, the Church of Christ is shining with the dual lights of Mary Magdalene, and His spotless bride Markella, for through divine will, they proceeded through their lives blamelessly, with manliness of mind, and pleased Him in a godly manner, and rightly became partakers of the glory on high. The one, hastened to anoint His spotless body with myrrh, and beheld the light of His Resurrection, bringing the good news to the saddened Apostles.  The other, fled the filthy will of her father, and was dyed scarlet through her blood of martyrdom and her purity. And they ceaselessly intercede on behalf of our souls.
