True community has nothing to do with idealistic expectations that everyone is loving or lovable all the time. One of the beautiful things about the Church is that it is, in essence, just a group of imperfect people that God has gathered together whose members have nothing in common but their commitment to him.
a quote from a PCA pastor http://www.citypres.org/involved.html

42 And they devoted themselves to the apostles' teaching and fellowship, to the breaking of bread and the prayers. 43 And awe came upon every soul, and many wonders and signs were being done through the apostles. 44 And all who believed were together and had all things in common. 45 And they were selling their possessions and belongings and distributing the proceeds to all, as any had need. 46 And day by day, attending the temple together and breaking bread in their homes, they received their food with glad and generous hearts, 47 praising God and having favor with all the people. And the Lord added to their number day by day those who were being saved.
