We do base our Mass on the everpresence of Christ.
Have you ever attended a Mass and listeened to the prayers?
As the article states -- it's about Christ being linked with Mary, His Mother.
I understand the term. I have been to a mass as well.
Christ, as eternally pre-existent God, had no mother in the normal sense of the phrase Mother. To most folks, it implies that Mary pre-existed Christ.
One can maintain the deity of Christ & humanity without giving Mary a title. Just discuss the person of Jesus. Mary is the mother of Jesus, who was/is/forevermore shall be God. But, Jesus did not pre-exist Mary, nor was their any divinity within Mary. His human nature was contributed to by Mary, but He came to her womb as God.
Luke 11:26-28,
"Then it goes and takes seven other spirits more wicked than itself, and they go in and live there. And the final condition of that man is worse than the first." As Jesus was saying these things, a woman in the crowd called out, "Blessed is the mother who gave you birth and nursed you." He replied, "Blessed rather are those who hear the word of God and obey it."
Mark 3:31-35,
"Then Jesus' mother and brothers arrived. Standing outside, they sent someone in to call him. A crowd was sitting around him, and they told him, "Your mother and brothers are outside looking for you." "Who are my mother and my brothers?" he asked. Then he looked at those seated in a circle around him and said, "Here are my mother and my brothers! Whoever does God's will is my brother and sister and mother."
