The problem with your interpretation of the passage
emphasis mine: AlegreFe
The problem you have is seeing that this is
my interpretation. It is not
my interpretation. It is that of the
Church which is that of the
Apostles.
What really saved Noah and his family?
Being on the ark which floated on the water. They were on the ark because Noah obeyed God to build the ark and he also had faith; if he didn’t have faith he would not have obeyed. So building the ark was part of his “works” to show his faith in God and obeying showed his humility & submission to God. So I would say all of the above. But one cannot be placed by itself without the other. Just like water & spirit cannot be separated and faith & works cannot be separated. We need both water & spirit and both faith & works to be saved. Again, that is not my interpretation. Those are the words of God. Read your bible and you will see.
Faith. They got on the ark because they believed and trusted in God.
Not faith alone! You totally disregard scripture and you talk about Catholics not knowing scripture.

First read my comments in this post; I stated “all of the above.” But we cannot have water alone or spirit alone or faith alone or works alone. We do not believe in this concept of “one or the other” we believe in “both… and…”
Second take into consideration the following passages in scripture;
1 Peter 3:18-21 (ESV)
18 For Christ also suffered once for sins, the righteous for the
unrighteous, that he might bring us to God, being put to death in
the flesh but made alive in the spirit,
19 in which he went and proclaimed to the spirits in prison,
20 because they formerly did not obey, when God’s patience
waited in the days of Noah, while the ark was being prepared, in
which a few, that is, eight persons,
were brought safely through
water.
21
Baptism, which corresponds to this, now
saves you, not as a
removal of dirt from the body but as an appeal to God for a good
conscience, through the resurrection of Jesus Christ,
John 3:5 (ESV)
5
Jesus answered, “
Truly,
truly, I say to you, unless one is
born of
water and the
Spirit, he cannot enter the kingdom
of God.
James 2:14, 20-22, 24, 26
14 What good is it, my brothers, if someone says he has
faith but does not have works?
Can that faith save him?
20 Do you want to be shown,
you foolish person, that faith
apart from works is useless?
21 Was not Abraham our father
justified by works when he
offered up his son Isaac on the altar?
22 You see that
faith was active along with his works, and
faith was completed by his works;
24 You see that a person is justified by
works and not by
faith alone.
26 For as the body apart from the spirit is dead, so also
faith apart from works is dead.
You’ll probably say something to the effect that because you have faith you will automatically do works. It doesn’t work that way. You show your faith with or by your works. It is not an automatic given that because you have faith you will do good works. Not everyone operates that way. Some will argue that since they already have faith, they don’t have to do anything; they are already saved. Not true. We have to have faith AND works.
In the same way, baptism follows faith in Christ.
True but not for everyone. If you’re an adult and came to believe in Christ and you want to get baptized because of that, fine. That’s what you are saying, I agree. But if you are baptized as an infant, you have already received the gift of the Holy Spirit, you have already been adopted by God, you have been cleansed of original sin, you have been made a member of Christ’s body the Church. But the parents have to raise the child in the faith or risk losing that child to the world or to protestantism or some other religion or cult. If the child is raised in the faith and comes to believe in Christ they can choose to complete the initiation with Confirmation on their own. My daughter was 14 when she was Confirmed. But she wanted to get Confirmed at a much younger age because she had already made the choice herself. She believed in Christ all on her own without any force from me.
If you read the passage with the emphasis on the ark instead of the water it makes more sense. The ark is a type of Christ. People were saved in the ark just like we are now saved through Christ.
I’m glad you brought that up. We think of the Church as our ARK! But being in the ark alone without the water & spirit and without faith & works is just like sitting in an empty ark with no navigator to make sure we are safe. We also consider the Church as Peter’s boat from where Jesus preached to the people. I like being in Peter’s boat! So in conclusion, passing through the water saved the people on the ark.
