And he took a pop at top aide Dominic Cummings over his plan to merge No10 and No11s political staff.
Mr Javid quit after being told he could only keep his job if he sacked his special advisers.
He told the Commons the power grab was not in the national interest.
Speaking truth to power is crucial for all Cabinet ministers, Mr Javid insisted, in a warning to the PM not to listen just to Yes Men.
His most biting criticism came over No10s bid to rip up Tory rules on borrowing and spending pledged in the election manifesto.
Mr Javid dubbed the fiscal rules to decrease Britains debt mountain by the end of the Parliament as critical.
He added: At a time when we need to do much more to level up across the generations, it would not be right to pass the bill for our day-to-day consumption to our children and grandchildren.

He suggested Mr Johnson must cut spending elsewhere if he wants to plough more into the NHS or police.
In what was seen as a dig at Mr Cummingss big spending plans, Mr Javid added: Its fair to say that not everyone in the centre of government feels the pressure to balance the books.
The PMs spokesman would only say: We will continue to have a clear fiscal framework, the detail of which the Chancellor will set out in the Budget.
