Behold thy mother: What Does Jesus Mean By Such Utterance in John
   19:26-27?

The teaching of the Roman Catholic church that Jesus entrusted his physical mother as the spiritual mother of the church is unfounded in these texts. In fact, that sort of interpretation is out of context.

Jesus entrusted his mother to the care of John (John 19:26,27).

Jesus did not entrust his mother to his siblings/ relatives because these were still unbelievers at that moment of Christ’s crucifixion (John 7:1-5).

Christians care for widows ( James 1:27).

Jesus considered not only his mother’s physical needs but also his spiritual needs when he entrusted his mother to the care of John.

Jesus did not give Mary to the church as its mother is evident in the other New Testament Scripture.

For Paul, the church/ Jerusalem is our mother:

But the Jerusalem that is above is free, and she is our mother (Galatians 4:26).
But we were gentle among you, like a mother caring for her little children. (1 Thessalonians 2:7).

For Paul, it is not Jesus’ mother who has been a mother to him:

Greet Rufus, chosen in the Lord, and his mother, who has been a mother to me, too(Romans 16:13).

Jesus himself refers to the church as his mother in the spiritual sense.He is telling us that blood relations are not what is important. It doesn’t matter if you are a relative of Jesus - as if that were something to boast about. . What is important is to hear the Word of God and obey.

"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." (Mark 3:33-35)

While Jesus was saying these things, one of the women in the crowd raised her voice and said to Him, “Blessed is the womb that bore You and the breasts at which You nursed.” But He said, “On the contrary, blessed are those who hear the word of God and observe it.” (Luke 11:27,28)

CONCLUSION

Jesus didn’t give his mom to be the mom of his church in John 19:26,27 for the context does not permit it. In reality, the first-century church does not give any evidence that Mary functioned as a mom to the entire church.
