What is the meaning of a Catholic Saint being "Raised to the Altar"?

For example, in entry **(150)** of her *Diary*, St. Faustina relates the following from a mystical conversation she had with St. Therese of Lisieux: > "Dear sweet Therese, tell me, shall I go to heaven?" And she answered, "Yes, you will go to heaven, Sister." "And will I be a saint?" To which she replied, "Yes, you will be a saint." "But, little Therese, shall I be a saint as you are, raised to the altar?" And she answered, "Yes, you will be a saint just as I am, but you must trust in the Lord Jesus." In the Catholic Church, what exactly is meant by the term "raised to the altar"? Does it mean *canonization* by the Pope? Are those declared *Blessed* (also) *raised to the altar*?
