A suggestion: Collect every scripture that addresses both God's singularity and plurality. This would require a word study including those texts in the original biblical languages. Don't forget the context and religious practices at the time. Group the collected texts according to the several authors. Of course, this would require time, effort, commitment, and above all else, spiritual honesty, and a willingness to alter one's view of God. Don't skip text you don't yet understand or don't like. I don't remember the nineteenth-century pastor's name, but I remember his wise comment, "If your view of God had not changed in five years, you're brain-dead." Seek spiritual growth.
If only all in Christendom would undertake such a study….but old doctrines, ingrained in believers by a tyrannical ”church” system, born out of a foretold apostasy, are not relinquished easily. Their shadow is cast over every truth, clouding their true meaning, and leading those who claim to be “believers” down a dark path. The “weeds” of Jesus parable have taken over the world….and the “sower” is delighted with his success.
Christendom is a fractured, disunited mess that pretends to the “the body of Christ”…..a dismembered body is of no use to the God whom Christ came to represent.
When Jesus returns as judge of all mankind, what will he find? Only “sheep and goats”……we are all to be judged as either one or the other….and according to Jesus, “few” will be found on the road to life. (Matt 7:13-14) The majority are therefore on the wrong road, and when taken to task over their claim that Jesus is their “Lord”, they will offer their excuses to Jesus who has rejected them. (Matt 7:21-23)
Why are they shocked at his rejection? They clung to the teachings of an apostate church, rather than to search for God themselves in his written word. The “church” that ruled the world for 1500 years, forbade reading of the Bible by the common people, who had no way to check whether they were being told the truth…..hence when the Reformation took place and the RCC lost its grip on the people, but the damage was too ingrained for people to shed the more important doctrinal lies that form the basis of all Christendom’s beliefs.
Set aside what you have been told to be the truth by your family members, your friends, pastors, bible teachers, etc. Try to clear your mind of the suppositions you bring to your study. Remember your highest priorities should be You, Your Bible, and the Holy Spirit, not someone else's Bible commentary - not even your own. Still, all of this promises to be a very difficult undertaking, and few are willing to undertake such a demanding study, being comfortable in what they already believe (and accept) as "the truth". If one "truly" understood everything they think they know about the Bible, they would be a spiritual giant.
You just described what happened at the end of the 19th century, when a group of like-minded men came together because of a common leading of God’s spirit to dispel all the errors they saw in Christendom’s teachings. They were from various backgrounds and denominations, so they were not seeking a breakaway from any one church, but a thorough investigation into the truth of those primary doctrines taught in the various churches, which they all seemed to share in their disunity.
They undertook such a study as you describe, dismissing all church doctrine and using only the Bible to furnish its own truth. It was a huge undertaking, but gradually they examined each doctrine and the scriptural evidence for it….and one by one, those false doctrines were thrown out and replaced by Bible truth.
It was important that they all speak in agreement, (1 Cor 1:10) and so every subject was prayerfully examined and considered with evidence from the entirety of Scripture to furnish a clear and solidly based Bible answer. Jesus and his apostles taught from the Hebrew Scriptures and so these were also carefully examined to ascertain their influence on Christ’s teachings. I also understand that no one can be a Christian in isolation as all must subscribe to one truth. Christianity was taught to those who became believers in Christ as “the son of God”. These met together for instruction and fellowship. (Heb 10:24-25)
It is a false impression to call the Bible “Old Testament” and “New Testament” as no Scripture is old or outdated, and none of Christ’s teachings were really ‘new’……what he introduced was a deeper understanding of Bible truths as they pertained to himself and his mission. He also clarified the choosing of his elect, and what their destiny would be.
Jews had no notion of going to heaven, even though they believed in the coming of God’s Kingdom….so the choosing of those who would be “kings and priests” with Christ in heaven was a new thought for them. Only with the outpouring of the Holy Spirit at Pentecost did those disciples fully understand their role and where they would serve with Christ in God’s Kingdom. (Rev 20:6)
These are my brotherhood, who have been growing in knowledge ever since. (Prov 4:18) We are a global brotherhood who are active in all nations “doing” what Christ commanded. (Matt 28:18-20; Matt 24:14)
Very few people will not know who Jehovah’s Witnesses are and very few will have good things to say about us….but we expect that as Jesus said….
John 15:18-21…
“If the world hates you, you know that it has hated me before it hated you. 19 If you were part of the world, the world would be fond of what is its own. Now because you are no part of the world, but I have chosen you out of the world, for this reason the world hates you. 20 Keep in mind the word I said to you: A slave is not greater than his master. If they have persecuted me, they will also persecute you; if they have observed my word, they will also observe yours. 21 But they will do all these things against you on account of my name, because they do not know the One who sent me.”
We are no part of Christendom, nor do we seek friendship with the world by compromising Christ’s teachings. (James 4:4; John 18:36)
I too have been a Bible student and teacher for over 50 years…..
