Are you saying man was created flawed and with a tendency to do evil, if you are, I would say you have a lot of explaining to do to let others know where you got that idea.
Second, no, the word sacraments and pergatory are not found in the bible, the ideas are.
The wedding feast at Cana- Obviously Jesus being there means He at least thought it was important, also all that stuff about What God has put together, let no man seperate.
So it looks like the idea that Marriage is graced is a good one
Confession- John 20:22- Whose sins you forgive are forgiven and whose sins you hold bound are held bound.
Now this may be just me, but if they had the authority NOT to forgive, then we better go and see if we are forgiven
Baptism- Go therefore and make disciples of all nations baptizing them in the name of the Father, and of the Son, and of the Holy Spirit- Matthew 28:19
The Eucharist-The last supper-The cup we use in the Lord’s Supper and for which we give thanks to God: when we drink from it, we are sharing in the blood of Christ. And the bread we break, when we eat it, we are sharing in the body of Christ.
1 Corinthians 9: 16
Also Check out John 6
Confirmation-When they arrived, they prayed for the believers that they might receive the Holy Spirit. For the Holy Spirit had not yet come down on any of them; they had only been baptized in the name of the Lord Jesus.
Acts 8: 14
hmmm, seems like grace is being given
Annointing of the sick- Is there anyone who is sick? He should send for church elders, who will pray for him and rub olive oil on him in the name of the Lord.
James 5: 14
again, looks like grace, and a ritual that the apostles founded
Holy orders- The group presented them to the apostles, who prayed and placed their hands on them.
Acts 6:5
Ok, let me give you the Catholic definition of sacrament-
An outward sign, instituted by Christ, to give grace.
As for purgatory-
… and the fire itself will test the quality of each one’s work. If the work stands that someone built upon the foundation, that person will receive a wage. But if someone’s work is burned up, that one will suffer loss; the person will be saved, but only as through fire.
1 Corinthians 3: 13
plus Maccabees, but since it is part of the apocrypha I will not include it.
The idea of a purifying fire is not a new one. You will be as gold tested in fire anyway, it makes sense that if we are to see an absolutely perfect God, we must be absolutely perfect.
So there you go, some biblical backing.

p.s. a just man falls seven times a day, so remember you are not perfect, nor am I
