The video "Faith in Action" tells many half-truths. One of them is the scene in which Rutherford presented the Finished Mystery for the first time at Bethel before many members, then some of them became angry on account of the book, and showed angry against Rutherford. This was a lie propagated by Rutherford and his friends, but if you read the transcription of the 1918 trial, Rutherford confessed that the book was not an issue initially in the dispute with the Society's directors. So, that scene is not historical. However, it was after some time that some Bible Students noted the rubbish written in the Finished Mystery, then some elders rejected its use. Accordingly, Rutherford imposed the acceptance of the book as a requisite to be an elder candidate. This was published in the Watchtower of that time:
...the Society has published and is wirlely distributing "The Finished Mystery"-Volume Seven of STUDIES IN THE SCRIPTURES. There is nothing in it out of harmony with the divine plan as revealed. The doctrines there taught are wholesome and clearly in harmony with that of the Lord Jesus Christ and the other six volumes of STUDIES IN THE SCRIPTURES. It is a part of the work of the SOCIETY to give this volume a wide distribution, because it is believed the due time has come for the message to be given against Babylon. A teacher that is opposed to the Seventh Volume, therefore, would be opposed to the SOCIETY'S work, out of harmony with the SOCIETY; and, as a leader, such an one would breed discontent and trouble, rather than establish harmony and peace and development among those of the Lord's people who had already expressed themselves as being in harmony with such Seventh Volume. Hence such an one should not stand for election to the position of elder.(The Watchtower, may 01, 1918, article: "Qualification of Elders", page 6220)
