God is the Truth. Jesus is the Truth. The Spirit is the Truth. Jesus even tells us His WORD is the Truth.
Truth is found in Scripture and only in that someone relies on Scripture, can anyone be sure that they will be in the truth as well.
The minute someone relies on extra-Biblical sources, such as tradition whether it's called *sacred* or not, they are going into error.
Your statement: “The minute someone relies on extra-Biblical sources, such as tradition whether it’s called *sacred* or not, they are going into error.”

Matthew 16:
18k And so I say to you, you are Peter, and upon this rock I will build my church,* and the gates of the netherworld shall not prevail against it. 19l I will give you the keys to the kingdom of heaven.* Whatever you bind on earth shall be bound in heaven; and whatever you loose on earth shall be loosed in heaven.”
