If they are true, then they should be found in the Bible and the Bible alone. The Bible admonishes us that it is fully complete in and of itself, needing nothing besides what it has already presented within it for us to gain wisdom and understanding.
[2Ti 3:16-17 KJV]
16 All scripture [is] given by inspiration of God, and [is] profitable for doctrine, for reproof, for correction, for instruction in righteousness: 17 That the man of God may be perfect, throughly furnished unto all good works.
Nicodemus considered the teacher of all teachers in his day came to Jesus by night and Jesus revealed to him the new birth. Nicodemus was well versed in all scripture all the way up until the time of Christ and yet he did not understand the new birth it had to be revealed to him he did not find it in Scripture.
There is an old covenant which was in effect until Christ died and rose again. Then there is the new Testament (covenant) from that time til the end of the age.
Hebrews 9:14-17 reads:
14How much more shall the blood of Christ, who through the eternal Spirit offered himself without spot to God, cleanse your conscience from dead works to serve the living God?
15And for this cause he is the mediator of the new testament, that by means of death, for the redemption of the transgressions that were under the first testament, they which are called might receive the promise of eternal inheritance.
16For where a testament is, there must also of necessity be the death of the testator.
17For a testament is of force after men are dead: otherwise it is of no strength at all while the testator liveth.
This new and living way had to be revealed it was unknown to the world up til that time.
