Do you consider old testament as scripture?
Discussion
I do not know how to answer your question, because I do not understand your definition of "scripture." It wasn't part of the first NT, until later, when the Judaizers stapled it onto the NT. IMO attempting to put a square peg into a round hole.
Let me put it this way; I do not believe YHWH, the God/Father of Israel, is the Father that was presented to us by Jesus.
YHWH ≠ JESUS (or His Father)
Where are you getting this teaching from?
No one is "teaching me", most people who read the whole OT/NT, if they're honest with themselves, will see a stark contrast between the entity called YHWH and Jesus (and the Father that was only presented to us via Jesus).
Jesus was crystal clear that no one knew His Father before Him, and only through Him do you know the Father;
Jesus said to him, “I am the way, and the truth, and the life. No one comes to the Father except through me. If you had known me, you would have known my Father also. From now on you do know him and have seen him.”- Jn 14:6–7
Everyone else were frauds; "All who came before me are thieves and robbers..." - Jn 10:8
When you start pointing this out, you're quickly labelled a Marcionite, as I was. Early on I didn't even know who Marcion was, and so I researched. Low and behold he was the first to create a NT and also saw that the God/Father of the Hebrew Bible wasn't the Father presented to us by Jesus. I also found out that the Marcionite Church was the largest and faster growing Church in early Christian history - hence why it was a threat and was targeted.
