Lyman Swingle should have known better. But then again, I can't say with certainty what his state of mind was in terms of actually twisting scripture or going with the majority.
Who we learned the good news of the Christ and the fundamental biblical truth should be of no consequence to you or anyone that is aware of the false teachings of the WTS. If that includes Lyman, then so be it.
Jehovah God knew we would experience this and therefore, we can take comfort in the following scriptures:
1 Corinthians 1:10-17 - ...
I appeal to you, brothers and sisters,[a] in the name of our Lord Jesus Christ, that all of you agree with one another in what you say and that there be no divisions among you, but that you be perfectly united in mind and thought. 11 My brothers and sisters, some from Chloe’s household have informed me that there are quarrels among you. 12 What I mean is this: One of you says, “I follow Paul”; another, “I follow Apollos”; another, “I follow Cephas[b]”; still another, “I follow Christ.” 13 Is Christ divided? Was Paul crucified for you? Were you baptized in the name of Paul? 14 I thank God that I did not baptize any of you except Crispus and Gaius, 15 so no one can say that you were baptized in my name. 16 (Yes, I also baptized the household of Stephanas; beyond that, I don’t remember if I baptized anyone else.) 17 For Christ did not send me to baptize, but to preach the gospel—not with wisdom and eloquence, lest the cross of Christ be emptied of its power.
And ..... 2 Corinthians 10:1-6 - ......
I myself, Paul, appeal to you by the meekness and gentleness of Christ—I who am humble when face to face with you, but bold toward you when I am away!— 2 I ask that when I am present I need not show boldness by daring to oppose those who think we are acting according to human standards.[a] 3 Indeed, we live as human beings,[b] but we do not wage war according to human standards;[c] 4 for the weapons of our warfare are not merely human,[d] but they have divine power to destroy strongholds. We destroy arguments 5 and every proud obstacle raised up against the knowledge of God, and we take every thought captive to obey Christ. 6 We are ready to punish every disobedience when your obedience is complete.
And .....John 8:32 - ......
...and you will know the truth, and the truth will make you free.
And .....John 8:40 - ......
....but now you are trying to kill me, a man who has told you the truth that I heard from God. This is not what Abraham did.
