One reason for the favorable article in the December 1940 Consolation regarding blood transfusions may have to due with Judge Rutherford's health at the time. He was suffering from cancer and had undergone several operations. Whether Rutherford required a blood transfusion during surgery is not mentioned in Watchtower publications.
But the fact that Rutherford permitted an article mentioning the benefits of blood transfusions indicates that he was not opposed to this medical procedure. Rutherford also exercised some control over Freddie Franz and his kookie ideas. However, once Rutherford joined Chuck Russell beyond the vale, Freddie was free to push his screwball opinions on the JWs, one of which was no blood transfusions for the faithful.
