QUES: In addition, Mahayana Buddhists believe there are innumerable other Buddhas in other universes.

QUES: Another misunderstanding is that, by her immaculate conception, Mary did not need a saviour. When defining the dogma in Ineffabilis Deus, Pope Pius IX explicitly affirmed that Mary was redeemed in a manner more sublime. He stated that Mary, rather than being cleansed after sin, was completely prevented from contracting Original Sin in view of the foreseen merits of Jesus Christ, the Savior of the human race. In Luke 1:47, Mary proclaims: "My spirit has rejoiced in God my Saviour." This is referred to as Mary's pre-redemption by Christ. Since the Second Council of Orange against semi-pelagianism, the Catholic Church has taught that even had man never sinned in the Garden of Eden and was sinless, he would still require God's grace to remain sinless.

Who said that Mary was cleansed after sin?

QUES: Around 1200 BC, the Dorians, another Greek-speaking people, followed from Epirus. Traditionally, historians have believed that the Dorian invasion caused the collapse of the Mycenaean civilization, but it is likely the main attack was made by seafaring raiders (sea peoples) who sailed into the eastern Mediterranean around 1180 BC. The Dorian invasion was followed by a poorly attested period of migrations, appropriately called the Greek Dark Ages, but by 800 BC the landscape of Archaic and Classical Greece was discernible.
