I did not say that Consecration of Bishops wasn't Biblical. I just couldn't find the consecration of Timothy and Titus in the Bible and wanted your scripture ref.
Veneration of Mary is NOT in Scripture period.
Our Lord made a mere seven statements from the Cross. For two thousand years, all Christian theologians have agreed that each of these statements is of monumental importance to us all. He did not simply speak just to pass the time, the hours on the Cross represented His sole purpose for being among us and to that end He wanted to emphasize the significance of His Crucifixion and explain things that we might not have understood on our own.
John was the ONLY apostle present; therefore, at that moment in time, John was the Church. When our Lord said, "Behold thy mother," He was not making "arrangements" for her, He was telling us to venerate her.
The Apostles were not going to abandon the Blessed Virgin Mary, Jesus didn't need to "remind" them to take care of her. And John didn't "need" a mother anymore after Christ's Death than he would have needed a mother before, so there must have been a need for this that John didn't yet understand.
No, it was much more significant, He was telling all of us that we needed to take Mary into our homes (hearts) as OUR Mother, that she is to be the Mother of the Church.
But for all of the doubters out there, maybe you should ponder this. Mary said that all generations shall call her "blessed." So, if you don't do this, why not? And why must you continue to diminish her significance? She carried our Lord in her womb and cared for Him when he was a child -- don't you think she could care for you as well? When all but one of His disciples fled in fear, she stayed at the foot of the Cross watching her only Son die -- why wouldn't you want her at your side?
Sure it is. "All generations shall call me blessed"; "a woman clothed with the sun, and the moon under her feet, and on her head a crown of twelve stars". You object to our interpretation of it, but it has scriptural roots.
