How has the christian movement changed from its early beginnings when the church was holding councils and discussing the theology of the holy trinity, to the church in modern times?

In the early days of Church it was a common practice for Church to meet and sit together at homes in small congregations, where they would eat and converse as it is stated in 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.” which in modern times has changed to reserve attitudes and the congregations only meet at some special or reserved occasions. Another thing which has changed is the usage of wealth which was for the wellbeing of poor and needy as said in 2 Corinthians 9:7...
"Each of you should give what you have decided in your heart to give, not reluctantly or under compulsion, for God loves a cheerful giver."
The practice no more exists in its true meanings.
