Nope, this isn't revoked, unless it's been revoked since March of this year. Per the March, 2016 WT, Questions From Readers:1919 is a revoked teaching.
Then, in 1919, Jesus appointed “the faithful and discreet slave” over God’s cleansed people to give them spiritual “food at the proper time."
Per previous explanations (from late 2012 onward), this appointment is only over the "domestics" while the appointment over "all my belongings" is still future. Phizzy is correct with this one.
1919 as an appointment of anybody by Jesus just has not one shred of real proof.
Yes, I agree.
