In the Christian churches of today it is common to call the Lord our Savior “the Son of Mary”; it is rare for people to call him “the Son of God” unless they mean the eternally begotten Son of God. This is a result of Roman Catholics putting Mother Mary’s sainthood above the rest and setting her up as the goddess or queen of all their saints.
Yet in fact, in the process of being glorified the Lord put off everything from his mother and put on everything from his Father, as we will fully demonstrate later on in this work [Sections 102–103]. Because the phrase “the Son of Mary” has become a common expression on everyone’s lips, many horrendous things have poured into the church. This is especially true of those who have not taken into consideration things said in the Word about the Lord—for example, that the Father and he are one, that he is in the Father and the Father is in him, that all things belonging to the Father are his, that he called Jehovah his Father, and that Jehovah the Father called him his Son.
The horrendous things that have poured into the church from our calling him “the Son of Mary” instead of “the Son of God” are that we lose the idea of the Lord’s divinity and we lose everything in the Word that is said about him as the Son of God. Furthermore, this concept lets in Judaism, Arianism, Socinianism, Calvinism in its original form, and finally materialist philosophy. Materialist philosophy brings with it the extreme position that the Son of Mary was Joseph’s child, or that his soul came from his mother, and as a result he is called “the Son of God,” but truly he is not. All people, both clergy and laity, should check to see whether the idea they have spawned and nurtured of the Lord as “the Son of Mary” is any different from the idea of him as a mere human being.
Already by the third century a concept like this was becoming prevalent among Christians, as the Arians were on the rise. To salvage divinity for the Lord, the Council of Nicaea made up “the eternally begotten Son of God.” Although it was a fiction, this concept did succeed at the time in elevating the Lord’s human nature to something divine; and it still works for many even today. It does not work, however, for those who see the hypostatic union as a union of two separate entities, one of whom is superior to the other.
What other outcome could this concept have but the destruction of the entire Christian church? The church is based entirely on worshiping Jehovah in human form; it is based on the Human God. The Lord states in many places that no one can see the Father, recognize him, come to him, or believe in him except through his human manifestation.
If people do not do this, all the church’s precious seeds turn into seeds of little value. Olive seeds turn into pine seeds; seeds from an orange, a lemon, an apple, and a pear turn into seeds from a willow, an elm, a linden, and a holly; seeds from a grapevine turn into seeds from a swamp rush; and wheat and barley turn into chaff. In fact, all forms of spiritual food become like the dust that snakes eat. Our spiritual light then becomes nature’s light; and in the long run it becomes the light of our physical senses, which is in reality a faint, deceptive light. Then we become like a bird that used to fly high but then its wings were cut off and it fell to earth; now as it walks around it does not see more than what lies at its own feet. Then when we think about the church’s spiritual teachings that are necessary for our eternal life, our thoughts about them are no more than the thoughts of a jester. All this is what happens when we regard the Lord God, the Redeemer and Savior, as no more than the Son of Mary, a mere human being.
