It seems as though at least one article in every issue of the study Watchtower is devoted to reinforcing the Governing Body's authority. This from pargraph 10:
10 Christ provides loving oversight of his congregations on earth by means of appointed elders. (Eph. 4:8, 11, 12) In the first century, all the overseers were spiritbegotten. They were depicted in Revelation as stars in Christ’s right hand. (Rev.1:16, 20). Today, most congregation elders are of the other sheep. They are appointed after prayer and under the guidance of the holy spirit, so they too can be regarded as under Christ’s direction, or guiding hand (that's a laugh, epecially when you know some really shady men have been appointed elders) . (Acts 20:28). They recognize, however, that Christ is using a small group of anointed Christian men as a Governing Body to lead and direct his disciples on earth.—Read Acts 15:6, 28-30.
I counted the number of times the term 'Govening Body' was used in the current study Watchtower (5 articles in all). It occurred a total of 8 times.
Also, did you notice that they are now capitalizing Governing Body? What arrogrance.
Of course, the teaching that Jesus is using a group of anointed Christians as a Governing Body has been always taught by the Witnesess based on the various NT descriptions of the 1st century Christian congregation.
However, the point is that this teaching is reinforced almost weekly now.
This was not the case 20, 15, or even 10 years ago.
The scriptural citation of Matt. 24:45-47, one of 2 verses in the entire Bible that mentions a "faithful & discreet slave" or equivalent, is included in at least 1/2 of of all study articles in the Watchtower.
It is also emphasized quite frequently in the Kingdom Ministry, Theocratic Ministry School, and every assembly and convention.
A couple dozen new songs in the latest songbook either outright praise the Governing Body, or at least mention "how wonderful and happifying it is to obey those taking the lead".
All of which begs the question: Since when does a slave have authority?
