Jesus prayed that all who would believe in Him would be one, sanctified (set apart) by the truth.
In the beginning, Jesus’ disciples loved one another following His example in one baptism, the remembrance of His death, and the washing of feet. And all drank of one Spirit, the Spirit of truth, the Spirit of God.
Jesus instructed His disciples to “make disciples of all nations… teaching them to observe all things that I have commanded you.” But within 150 years, new teachings, including the observance of Easter, were declared as “doctrines” of the Church to Emperor. The Church was no longer united by the example of Jesus and His teachings.
The Abomination of Desolation
In 193, the Bishop of Rome wrote letters of excommunication to the churches of Asia because they disagreed on the observance of Easter, and the evidence of the Holy Spirit, and the Spirit of truth, was taken from the Church.
The saints were given into the hand of the Antichrist for time, times and half a time, 3 1/2 years, or 1278 days, as years, from 193 until 1471, when the first Protestant Denomination broke free from the Papacy.
By His Spirit, God is showing the way to unity, “that the world may believe that You sent Me.”
