Do you consider yourself someone who keeps the Commandments?

CP,
What I've never been sure of is how Jesus telling one of his 12 apostles to behold his mother in Mary, and Mary to behold him as her son has been taken as Jesus telling us all to behold Mary as our mother.

There are several explanations for this.  But for this, we have to go deeper into Scripture than Protestants are accustomed to do.

First, Scripture tells us to go beyond the letter to the Spirit of the Word:
2 Corinthians 3:6 (KJV)
6 Who also hath made us able ministers of the new testament; not of the letter, but of the spirit: for the letter killeth, but the spirit giveth life.

Because the truths of Scripture are spiritually discerned:
1 Corinthians 2:14
King James Version (KJV)
14 But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because they are spiritually discerned.

So, let us go to the spirit of the text in question.

First:
John 19:26-28
26 When Jesus therefore saw his mother, and the disciple standing by, whom he loved, he saith unto his mother, Woman, behold thy son!  27 Then saith he to the disciple, Behold thy mother! And from that hour that disciple took her unto his own home.  28 After this, Jesus knowing that all things were now accomplished, that the scripture might be fulfilled, saith, I thirst.

Catholics are taught to read Scripture as though God was speaking to us.  Now, are you a beloved disciple of Christ?  To put it differently, are you a disciple whom Jesus loves?

Catholics would answer, "Yes" to that question and therefore accept Jesus command to take Mary as our mother and bring her into our home (i.e. heart).

For the second part of this explanation, you need to be aware of other verses in Scripture.
Genesis 3:15
15 And I will put enmity between thee and the woman, and between thy seed and her seed; it shall bruise thy head, and thou shalt bruise his heel.

The seed of the Woman is not just Jesus.  Let me show you:
Revelation 12:17
17 And the dragon was wroth with the woman, and went to make war with the remnant of her seed, which keep the commandments of God, and have the testimony of Jesus Christ.

Do you consider yourself someone who keeps the Commandments of God and the testimony of Jesus?  If so, then you are seed or a child of the Woman.  That Woman is Mary.  And therefore, Scripture says that all who fight the good fight on behalf of God in Christ, are children of Mary.

That's my story and I'm stickin' to it.

Sincerely,

De Maria
