I'm going to take DMorgan up on his cites. Are you saying that the one who holds out to the end, the same shall be saved?
If you read the Old Testament, you will notice the our Holy God severely chastised the Jews numerous times for disobeying His comandments. God always preserved a holy, faithful remnant to fulfill His promise to Abraham, Solomon, and David. All of the ancient prophets fortold of coming chastisements to the jews due to their repeated unbelief and turning away. The Teachings of our Lord in the New Testament are no different. Just as the Consecration says "For Many" not all church militant will hold on to the faith. We see this around us constantly. The changes to Holy Mother Church since V-II have led many souls to hell, and many more will follow.
The Holy Gospel according to St. Mathew, chapter 24:
"6 And you shall hear of wars and rumours of wars. See that ye be not troubled. For these things must come to pass, but the end is not yet. 7 For nation shall rise against nation, and kingdom against kingdom; and there shall be pestilences, and famines, and earthquakes in places: 8 Now all these are the beginnings of sorrows. 9 Then shall they deliver you up to be afflicted, and shall put you to death: and you shall be hated by all nations for my name's sake. 10 And then shall many be scandalized: and shall betray one another: and shall hate one another.
11 And many false prophets shall rise, and shall seduce many. 12 And because iniquity hath abounded, the charity of many shall grow cold. 13 But he that shall persevere to the end, he shall be saved."
The sins of many, inside and outside of Holy Mother Church has purchased this chastisement, but we can persevere to the end. Pray for God to restore Holy Mother Church.
