With all due respect to you, Gunnar, you have completely missed the point. The reference is to actual resources being withdrawn from circulation by the financial act of saving. It was a point made by others before Keynes. See attachment below. The theorem that loans create deposits means simply that the rate of loan creation equals the rate of deposit creation, assuming steady-state.
Bank credit is a subset of the more generalized concept of credit.
There are many examples of credit that do not materialize as bank deposits. Additionally, bank deposits can arise from sources other than bank loans. An obvious example is from counterfeiting. When the Shaw abdicated the Bank of Iran was left in the possession of printing presses superior to those owned by the American Banknote Company, which prints currency for several nation-states. They also had stores of paper practically indistinguishable to the paper then used in Federal Reserve Notes.
