Doctrinal development (theology) began immediately in the early Church with the preaching of the Apostles. The Bishops and theologians down through the centuries have all contributed to it, with certain famous theologians such as St. Augustine standing head and shoulders above the rest. But the most famous theologian in all of Christian history is St. Thomas Aquinas from the thirteen century. Christian theology today is still taught from St. Thomas Aquinas, see link below.
In the first couple of centuries the church was probably pretty loosely organized. Most local churches would have appointed men and women who oversaw the spiritual growth of the individuals in the congregation.
There was not necessarily anyone "in charge" in terms of a pastor or other person running the gatherings.
Unless there was a visiting speaker eg. an Apostle or other traveling teacher, they would have met in homes with the focus being on Yeshua (Jesus) and His teaching along with reading and teaching of scripture if a copy was available.
Probably, no two gatherings were alike. Each time was marked by a flow of the Holy Spirit that led the gathering. While there would have been order, it would not have been ordered. In other words, the flow was there but no one had an idea where it might go next.
Anyone, from youngest to oldest could have shared a psalm or song, a dream, a prophetic encouragement, some insight from scripture etc. Everyone was expected to participate and wanted to be since no one was judged for immaturity but encouraged where they were so they were able to grow quickly.
If there was any sort of organizing it would have been around the meal. This was integral and where they would have shared and fellowshipped throughout the day and well into the evening if it was The Sabbath.
They were in each others lives. There was covenant. Very much like marriage, they looked out for one another, cared for one another. The thing they would have been known in the community for was the great love they had for each other as well as those they were in contact with each day within the community.
The first church was started by Paul.
Was organized when? The church in the 1st. or 2nd. century was quite different from the church in the 10th. century, for example.

No, because it is the Orthodox Church that determines correct doctrines, dogmas and teachings. The church fathers were orthodox theologians within the church, and not on their own. This is what distinguishes the Orthodox from other Christian groups, such as the Protestants, where anyone can study theology and call themselves a theologian. This does not exist in Orthodoxy, as theology and the church are one.
