Before considering the question of why there are so many churches and Denominations, it is necessary to recognize that there has only been one perfect person who has ever walked this earth, and that is Jesus the Christ. Every one else comes under the heading of a “sinner saved by grace” or someone who could be a “sinner saved by grace” if they ask the Lord for salvation.
Some people are born into a certain congregation or denomination. They are taught their viewpoint is right and all others are wrong. It may be difficult for such people to learn anything to change that, because their system becomes a closed system, closed to all other information, prophecies, visitations, and historical leadership.
That may be why “Jesus saith unto them, Verily I say unto you, That the publicans and the harlots go into the kingdom of God before you.” Matthew 21:31b
In other words, the publicans and harlots were not steeped in religious tradition or bound by church members who would shun them if they peeked outside the church walls at the church next door. The publicans and harlots were able to Hear what “the Spirit saith unto the churches”.
“He that hath an ear, let him hear what the Spirit saith unto the churches.” Revelation 2:29
This is not to say that tradition is necessarily a bad thing. It is only a bad thing if it pre-empts being able to hear the Lord directly and being open to hearing and seeing what the Holy Spirit is doing.
Traditions passed on from the elders of the faith, that were received by revelation, are good if continued. The Lord’s Prayer is as relevant today as when Jesus first gave it. Some things do not diminish with time or age.
The Bible is a document of revelations.
For the prophecy came not in old time by the will of man: but holy men of God spake as they were moved by the Holy Ghost. II Peter 1:21
There were confirmations in the lives of these people that that they were in connection with God and actually did hear God. Moses did lead the children of Israel out of Egypt, as God said he would. Joseph’s dream of his brothers bowing before him was Confirmed after man years. Mary’s visitation was confirmed and she was the mother of Jesus. Joseph’s dream was confirmed that he needed to take Mary and Jesus to Egypt to flee the persecution of babies under 2 years old. Zachariah’s visitation from Gabriel was confirmed and his wife Elizabeth, up until then “barren”, did bear a child in old age named John (the Baptist). Abraham’s visitations were confirmed. These are just a few of the many events where Heaven touched earth in a supernatural visitation.
Of course, the major confirmation, which precedes and confirms all of the others, is that of Jesus the Christ. There are over 300+ prophecies of his birth, life, death, resurrection, and mission. Since these were or are being confirmed, it confirms the validity of the Bible as a whole. The probabilities of 300+ spontaneous events happening in the life of one individual are too great for anything but a divine visitation.
The point is, the Bible is a book of revelations from God to man. So today’s denominations come back to revelation, faith, and obedience. Does someone believe a revelation? Will someone have faith in it? Will someone obey it?
The various denominations shake out at various degrees of believing revelation from God, having faith, and obeying revelations. And, over time, as people grow, they may expand their beliefs or revelations, and thus move to a different denomination or branch of Christianity. Again, this is not necessary bad. It can involve positive growth. If the relationship with the Lord is getting stronger, that is the main thing.
In other words, some people believe God heals today. Some denominations don’t. The day may come when someone who believes that healing was limited to the time of Jesus the Christ and the apostles moves into the camp of believing the God heals today. This just means there was an opening of revelation and faith.
It is better to accept that, like life itself with its levels of growth and difference between peoples, people are at different levels of understanding spiritually. Instead of fighting different denominations, focus on the commonalities like Jesus is Lord and did come as the Saviour and Redeemer of the world through His death, burial, and resurrection. He is coming again to rule and reign. Meanwhile, let people grow in the grace and knowledge of our Lord Jesus Christ. As people hear the Lord for themselves, they will grow.
