He's in a marriage that the church does not recognize among other contradictions of the faith...
From N.J. Bishop: No Communion for Governor | theledger.com:
"The Most Rev. Joseph Galante said Thursday that he was taking the stance primarily because the Democratic governor remarried without receiving a church annulment.
Galante also cited McGreevey's support of abortion rights, stem cell research and other positions that contradict church views.
Galante, who was installed Friday during a Mass at St. Agnes Church in Blackwood, said he felt duty-bound to take a hard-line stance on the issue. He said the public becomes confused about church teachings when bishops fail to challenge Catholic politicians on their voting records."
