“It will be discovered that so called Christians who think they believe in the Divinity of Christ but do not believe in Mary as the Mother of God fall generally into four ancient heresies. They are Adoptionists, who believe that Christ was a mere man but after birth was adopted by God as His Son. Or they are Nestorians, who held that Mary gave birth to a man who had a close union with Divinity. Or they are Eutychians, who decided the human nature of Christ and hence made Mary merely, an instrument in a theophany. Or they are Docetists, holding that Christ’s nature was only a phantom or an appearance. Those who are offended at reverence paid Mary, if they will analyze their thoughts, will discover that they are holding a Docetist or some similar ancient error. Even if they profess the Divinity of Christ in His earthly existence, such people shrink from affirming that His human nature is glorified with Him at the right hand of the Father, where He makes intercession for us. As some no longer think Christ as God, so some no longer think of Christ as a glorified Man. If He is no longer Man, the relation of Mary to Him extends beyond Bethlehem and Calvary even to His Mystical Body the Church. No one, therefore, who thinks logically about Christ can understand such a question as: ‘Why do you speak so often of His Mother?’ ” (The World’s First Love, pg 71)
