Jesus does not start with Mary, He was from the beginning. Jesus is incarnate, that is taking a human nature. Mary is not the mother of God. Our God is a Trinity, and when we say Mary is the mother of God, we err as God is not synonymous to Jesus.
By God, we are simply saying that Mary is the mother of the Father, the Son and the Holy Spirit.
The line of believe is suspect.
During the last supper, Jesus said this is my body, then ate it. Thus he ate his body and drank his blood. Was his body in the bread by then?
The disciples also ate the bread and drank the wine while still with Jesus. Was Jesus in the bread and at the same time with them, or both?
Acts:1:14: These all continued with one accord in prayer and supplication, with the women, and Mary the mother of Jesus, and with his brethren.
Acts:2:46: And they, continuing daily with one accord in the temple, and breaking bread from house to house, did eat their meat with gladness and singleness of heart,
Mary was in the company of the first Apostles, and they ate the Lord’s table together. If they perceived that Jesus was in the bread, it must have been a bitter reminder to Mary that she was eating her son every time.
The Apostles saw Jesus die and rise again, they could not have perceived that he was in the bread whereas they knew that he had ascended to heaven.
If its obvious, what would be the objective of it being put in the Revelation. Unless Jesus wanted to prove to the world that Mary is in heaven and is the queen of heaven. Otherwise, nothing else is deduced from the whole chapter.
However, some sections are intentionally omitted in this interpretation.
Rev:12:6: And the woman fled into the wilderness… for 1,260 days
Rev:12:14: And to the woman was given two wings of a great eagle, that she might fly into the wilderness, into her place, where she is nourished for a time, and times, and half a time, from the face of the serpent.
What is this wilderness place?
What is these 1,260 days?
Is the woman still at her place in the wilderness?
Does the woman has wings?
This is one of the latter doctrines that were adopted in the Catholic church among many others. The book of Acts narrates the deeds of the Apostles. As Mary was still alive, converts never considered her as their spiritual mother. They were baptized in the name of Jesus and were filled with the Holy Spirit. They looked unto Jesus, the beginner and finisher of their faith.
In the book of Revelation, there are names of 7 different churches.
Apostle Peter wrote to believers scattered in Pontus, Galatia, Cappadocia, Asia, and Bithynia. There were churches there.
Apostle Paul opened very many churches, and even wished to go to Spain and preach the Gospel there.
The objective is not about the number of churches as the the command of Jesus in Matt:28:19: is to go and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:
The main Question is whether they uphold the teaching of Christ. The Bible is sufficient to make a believer know Christ and reach heaven.
