I do not conceive of the Church as amorphous but I do not believe that there is such a thing as structural sin. It is only individuals who commit sins, individuals within structures, organisations and institutions and it will be those individuals who will be judged individually not the institutions. To say the Church sins implies that it will be judged as an institution which opens up the ridiculous possibility of the whole People of God, with which you equate the Church, being found guilty and condemned.
I don't see God as quick to condemn, Gods forgiveness and mercy is extended to all who repent of their sins and seek to do His will. You make these accusations and judgements of me simply because I disagree with your particular concept of God which is not a Catholic concept. The only relationship with God we can have is through His Church, we cannot separate God from His Church which is what you are attempting.
