I’ve never understood the denial of communion to people who have divorced and remarried. The Catholic Church freely hands the wafers to apostates like Nancy Pelosi and murderers and fornicaters, but if you divorce and remarry, you are effectively excommunicated.
Somehow the sin of divorce has been deemed by the Catholic hierarchy to be the functional equivalent of blasphemy of the Holy Spirit.
Prohibiting a person from a sacrament that is deemed to be essential to salvation is the equivalent of damning that person to hell.
