The need of sacrifices for sin. The view of women and their place in the church. Views on authority of the church. Ect.
I will respectfully disagree and state that the bible's timeless principles remain outdated.
Jesus nor his followers ever even knew of the bible or scripture. The cannon was made some three hundred years after the man he was based off of died. The vast majority of what we know of Christianity developed out of Paul's writings and the four authors of the gospels who were more than likely not first person eye witnesses.
You may believe what you will.
The Mosaic Law sacrifices showed that No one could remain sinless, thus the need for Messiah to come.
The counsel given three times for the Corinthian congregation for those women to keep silent was for the same reason at 1st Cor. 14:40 that all things should take place decently and by arrangement. Not meaning never to speak, but there was a time to be silent.
Men were given the position to take the lead. If a woman did Not understand something, she was Not to disrupt the congregation meeting, but first she would go to her husband, then if it was still unresolved, then they would go to the spiritually older men in the congregation.
The Hebrew Scriptures are and were very much older than the Christian Scriptures.
By age 12 - Luke 2 vs 42 - 47 - Jesus already was educated in those old existing Hebrew Scriptures.
By Jesus saying ' God Word is truth ' - John 17:17 - Jesus meant the the words already recorded in the old Hebrew Scriptures.
Jesus even quoted or referred to those old Scriptures when rebuking Satan at Luke chapter 4. See verses 4,8,10,12; Deut 6:16
Starting from the time of Moses to Christ the Constitution of the Mosaic Law was in existence.
Jesus often prefaced his statement with the words, " it is written " meaning already written down in the old Hebrew Scriptures.
- Matthew 4:4,7,0; 11:10; 21:13; 26:32; Mark 9:13; 14:27; Luke 24:46; John 6: 45; 8:17
The Bible is full of corresponding cross-reference verses and passages between the Hebrew and Christian Greek Scriptures.
Bible canon was completed by gospel writer John at the end of the first century.
Constantine set up Christendom - false Christianity - in the 3rd century.
It is more like one gospel according to four writers:
The gospel according to Matthew
The gospel according to Mark
The gospel according to Luke
The gospel according to John
What I meant by forever timeless principles for example is what is recorded at:
Matthew 7:12 - the Golden Rule
Be mild, kind, compassionate - Colossians 3:12
Conquer evil with good - Matthew 5:44; Romans 12:21
Love neighbor - Matthew 22:39
Honor or respect others - Romans 12:10
Pursue peace - Mark 9:50; Romans 12:18; 14:19
Be forgiving - Matthew 6:12
Be loyal- Proverbs 5 vs 15-20
Be honest - Micah 6:11
Be truthful - Amos 5:15; Zech. 8:16; Ephesians 4:25
Be a good worker - Proverbs 22:29; Colossians 3:23
