I'm still not convinced that using condom warrants a same treatment as promoting legal abortion. They both may be against the Church teachings, but defying communion is a serious punishment.
Promoting abortion brings with it an automatic excommunication. Using a condom does not. However, Communion is not a universal right for Catholics. You must be in the state of grace and free from all serious sin. Using contracepives is a serious sin in the church. It is one out of many serious sins.
I believe he would deny communion on the basis of birth control other than condoms..although that is not specifically stated.
