Whole counsel of God is found in Scripture... with nothing added.
I for one welcome a commitment to the whole counsel of God. Including this passage from Paul...
Ephesians 2:8-9
“For it is by grace you have been saved, through faith—and this is not from yourselves, it is the gift of God— not by works, so that no one can boast.”
No sacramental system of a “treasury of merit” exists, nor is needed for salvation.
I have literally heard that from a daughter of a Minister, when she engaged in adultery.
“Whole counsel of God is found in Scripture... with nothing added.”
Remember Stephen, his wisdom did not come from the scriptures...
Acts 6:”10 But they could not stand up against the wisdom the Spirit gave him as he spoke.”
Per James 3:
There are Two Kinds of Wisdom
13 Who is wise and understanding among you? Let them show it by their good life, by deeds done in the humility that comes from wisdom. 14 But if you harbor bitter envy and selfish ambition in your hearts, do not boast about it or deny the truth. 15 Such “wisdom” does not come down from heaven but is earthly, unspiritual, demonic. 16 For where you have envy and selfish ambition, there you find disorder and every evil practice.
17 But the wisdom that comes from heaven is first of all pure; then peace-loving, considerate, submissive, full of mercy and good fruit, impartial and sincere. 18 Peacemakers who sow in peace reap a harvest of righteousness.
