The Church did exist before the bible was fully written, but the Holy Spirit had a much more active role in those days, as the bible clearly states, to help everyone out. We don’t have the same spiritual gifts in the same quantity as the first century Christians did back then and I feel the reason was because they didn’t have the new testament to rely on.
We know they were temporary gifts.
1 Corinthians 13:8-10
Love never fails; but if there are gifts of prophecy, they will be done away; if there are tongues, they will cease; if there is knowledge, it will be done away.
For we know in part and we prophesy in part; but when the perfect comes, the partial will be done away.
I’m not going to use this post to argue for or against sola scriptura, but to simply say that Church tradition must always be harmonious with the written word. I don’t believe Catholics reject that notion that they should be in agreement. So I do take issue when a tradition is entirely unbiblical. Not to say that it’s outright sinful, but that it has no basis in scriptural authority.
The pharisees has a lot of traditions and rituals they used that weren’t necessarily sinful. Jesus called them on their hypocrisy, not their use of rituals necessarily. But the traditions they used didn’t profit them anything either since it was never mandated. At least that is my understand of the matter.
