I don’t consider this a “nuclear option,” I consider it the “last option!”
When you PUBLICLY deny the teachings of Christ and refuse to bow to the truth then it is for the good of the faithfull that the Chruch stand for the truth as taught by Christ. What message would that have sent if the bishops said - ok, you can still receive the Eucharist even though you are publicly telling everyone here you are living in a homosexual relationship? or that you publicly support the lifestyle?
St. Paul says in 1 Cor. 11 27:29 - Therefore whoever eats the bread or drinks the cup of the Lord unworthily will have to answer for the body and blood of the Lord. A person should examine himself, and so eat the bread and drink the cup. For anyone who eats and drinks without discerning the body, eats and drinks judgment on himself.
Homosexuality has been deemed as a grave and disordered sin by God since the beginning of salvation history. Now, would it be right for the priests/bishops to let those people eat and drink jugment on themselves? And would it be right for you as a believing Catholic to watch your Church say it’s ok for these people to receive the Eucharist when you are trying your best to live a Christ centered life? How unfair is that? They cannot have their cake and eat it, too! They either believe or they don’t.
It’s not right for these people to put the Church in a stuation like this - having to publicly deny the Eucharist but what other choice did they have? You must be in a state of grace when receiving the sacraments, besides Reconciliation. When you present yourself for the sacraments, you are “dying with Christ to rise with Christ” meaning that you promise to live a “Christ-like” life. It don’t consider an actively homosexual relationship doing that. And if you are going to proclaim it publicly then you deserve the reprimand for the good of the faithful!
When you decide to come back to the truth, repent AND receive absolution, then you can present yourself at the table of the Lord, to receive the Body and Blood of the Lord. Until then, you don’t present yourself.
