Return to tradition.
Return to the unchangeable and inspired Scripture.
That includes Scripture, precious and irreplaceable, unchangeable and inspired, which is the written Tradition.
You objected to that, so I explained what Rao meant. It's evident he meant a return to the sources of Christian doctrine, and that would be the tra-ditio in the big-T sense, what was handed down to us from the Apostles. (He was not talking about Hot Cross Buns.)
In the historic Christian sense, that would include the Apostles' teaching, their written memoirs, the way of prayer and way of life they transmitted to the original Christian communities.
As you can see, that comprises Scripture (the part that was written down by the Apostles' own hand or by their scribes) as well as their preaching and example.
My original point may have been poorly stated and thus open to misinterpretation, but thank you for letting me --- with a fresh coffee in front of me --- try again.
I mean “Dr. Rao”.
