Are These Christians?

I, for one, don't think so:

From Acts, Chapter 2:

44 And all that believed were together, and had all things common;
45 And sold their possessions and goods, and parted them to all men, as every man had need.
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,
47 Praising God, and having favor with all the people. And the Lord added to the church daily such as should be saved.
