The first affirmation Jesus Christ intended for those who do the will of the Father to be His mother is found in the Gospels.  Three of the Gospels recount when Jesus once being informed that His brothers, sisters, and mother are outside.   Jesus responds by raising His hand over His disciples while stating that, “Anyone who does the will of the Father are my brothers, sisters, and my mother.”  See Mark 3:31-35, Matthew 12:46-50, Luke 8:19-21

 

Blessed Isaac of Stella (ca. 1100AD – 1169) entered the Cistercian Monastery of Citeaux of France.  Isaac be became an abbot of the Cistercian monastery of Stella.  He was known for his holiness and the teachings he gave his monks on the spiritual life. (See http://www.crossroadsinitiative.com/library_author/90/Isaac_of_Stella.html and the Liturgy of the Readings)

 

Blessed Isaac of Stella is one who later highlighted this statement of motherhood to Jesus when in a sermon of his he wrote the following:

 

In a way, every Christian is also believed to be a bride of God’s Word, a mother of Christ, his daughter and sister, at once virginal and fruitful. These words are used in a universal sense of the Church, in a special sense of Mary, in a particular sense of the individual Christian. They are used by God’s Wisdom in person, the Word of the Father.
     This is why Scripture says: I will dwell in the inheritance of the Lord. The Lord’s inheritance is, in a general sense, the Church; in a special sense, Mary; in an individual sense, the Christian. Christ dwelt for nine months in the tabernacle of Mary’s womb. He dwells until the end of the ages in the tabernacle of the Church’s faith. He will dwell forever in the knowledge and love of each faithful soul.  

 

Here Blessed Isaac of Stella relied on what Jesus said.  Blessed Isaac of Stella saw the reference in physical terms for the Blessed Virgin Mary while he saw this comment in spiritual terms for the rest of the members of the Body of Christ, the Church.  Clearly this is further validation for a devotion to the Preborn Christ who Christians bear Liturgically and Sacramentally and are destined to become the on-going incarnation of Jesus Christ.
