How Much Does the Modern Church (your church) Resemble the Church Christ Established?

Below is what the church looked like right after the Holy Spirit came at Pentecost. What have we retained or lost of this simple model for church? I hesitate to call it a model, because I don't think they were thinking/talking that way about it. More likely, it was how they were led by the Spirit and what made sense based on who they were in Christ. Where are the programs? Where are the committees? Where are most of the things we call church? The things I just mentioned aren't bad, but do we have time/energy left to do the main things for which the church exists?

Acts 2:40 And with many other words he testified and exhorted them, saying, “Be saved from this perverse generation.” 41 Then those who gladly received his word were baptized; and that day about three thousand souls were added to them. 42 And they continued steadfastly in the apostles’ doctrine and fellowship, in the breaking of bread, and in prayers. 43 Then fear came upon every soul, and many wonders and signs were done through the apostles. 44 Now all who believed were together, and had all things in common, 45 and sold their possessions and goods, and divided them among all, as anyone had need.
46 So continuing daily with one accord in the temple, and breaking bread from house to house, they ate their food with gladness and simplicity of heart, 47 praising God and having favor with all the people. And the Lord added to the church daily those who were being saved. (NKJV)
