What that has to do with my statement about the Catholic Church proclaiming Holy Scripture is the Word of God, I don't know. But to humor you, I'll try to answer you.
We first hear about a man named Simeon in Luke 2, when Joseph and Mary present the Christ child at the temple to dedicate him to the Lord as was the custom.
Luke 2:25-35 Now there was a man in Jerusalem called Simeon, who was righteous and devout. He was waiting for the consolation of Israel,* and the Holy Spirit was on him. It had been revealed to him by the Holy Spirit that he would not die before he had seen the Lords Messiah. Moved by the Spirit, he went into the temple courts. When the parents brought in the child Jesus to do for him what the custom of the Law required, Simeon took him in his arms and praised God, saying:
The childs father and mother marveled at what was said about him. Then Simeon blessed them and said to Mary, his mother: This child is destined to cause the falling(***) and rising of many in Israel, and to be a sign that will be spoken against, so that the thoughts of many hearts will be revealed. And a sword will pierce your own soul too.
* The "consolation of Israel" is spoken of in Isaiah 52:9:
** The "glory of your people Israel" is spoken of in Isaiah 42:6
And Isaiah 49:6:
*** Simeon saying, "This child is destined to cause the falling and rising of many in Israel" is a reference to Isaiah 8:14, which says:
So, to answer your question, this guy Simeon sounds like a very righteous and devout Jew who knew his Scripture well, was looking for the coming Messiah, the Holy Spirit was "on" him and, as Luke said, "It had been revealed to him by the Holy Spirit that he would not die before he had seen the Lords Messiah." (Luke 2:26) See, not only did Simeon KNOW to look for the Messiah because of Scripture, but he also had a special revelation - a personal revelation - that he WOULD NOT die until he saw the Messiah. The Holy Spirit confirmed within his heart that Jesus was the Messiah and he knew that he could die in peace having seen the chosen one of Israel.
Luk 2:29 Lord, now lettest thou thy servant depart in peace, according to thy word:And that while the scripture clearly states "the Holy Ghost was upon him" in verse 25.
Maybe you need a better Bible.
