President [N. Eldon] Tanner mentioned proposed changes in the dialogue in the temple rituals, some of which he said had been implemented and some will be implemented on the tape and film that are being prepared. He said that some of these are intended to save repetition and others to clarify the statements made. He said the changes proposed were minor, and mentioned one or two changes as an illustration of what it is proposed to do.
President Tanner said that a few of these suggested changes had been presented to President McKay some time ago by Elder ElRay L. Christiansen and had received his approval.
Elder [Harold B.] Lee said that we must assume that all that has been done is under the inspiration of the Almighty to the Presidency and the Twelve, which is the legislative body of the Church. He said, "If you will tell us that you have that inspiration and you now bring that for our approval, I will have no question, but when you sit down to make changes in some things that we have had for a whole century, I have some reservations."
The brethren discussed at some length the various parts of the ceremony and proposed changes, but there was some opposition expressed to the proposal to make changes at this time, especially without reading carefully and discussing the proposed changes.
Elder [Marion G.] Romney said he had confidence in the President, and that everything he says he would sustain. He also had great confidence in President Tanner and the other brethren, and was willing to rest on their judgment, but he did not want to pass on anything without knowing what it is. He said he was willing to leave it to the committee if it is thought that is what should be done, but if they wanted his opinion on it he had to know what it is, and wouldn't want to vote to pass this as long as there was one person in the Council who questioned it.
