I am a Christian - I became one at 5 years old.  I have always believed in God, that Jesus is God's son, He died and rose to save us from sin, etc.  I have not always been as strong in my faith and practiced it to the extent that I should, but I believe that God is gracious and good and forgiving.  Something that people tend to forget about churches when they decide to go off on a tirade:  Churches are full of PEOPLE.  People don't become perfect and less human when they practice a religion or faith, yet sometimes a person can be so quick to blast them for offenses that the person theirself is practicing.  I don't agree with everything my church teaches, and I believe that it is the responsibility for every person to give a thorough and intelligent answer when asked why they believe what they believe.
My brother grew up southern baptist, and now thinks he's Catholic.  He goes to Mass once a year, and married a Catholic girl (who was not practicing) and my nephew was christened in a Catholic church.  Evidently, all this makes him Catholic.
