Kevin,
Why should we think that one day Jesus will walk back what He said about marriage and treating our bodies as His temples? Our bodies are Jesus' temple, where like the Blessed Mother (the first Tabernacle) we carry Jesus after receiving Him in the Holy Eucharist and like Joseph, his foster father, we are to protect Jesus in His temple! We are not to desecrate the body of Christ. This is a sin. I remember going to Confession a few years ago and confessing that I had not confessed that during many years of living in sin (against purity), I was receiving Jesus in the Holy Eucharist. I am glad I confessed this. I do not think it is a good idea for people to receive Jesus in the Holy Eucharist without the intention of changing their lives/repenting of sin. Should one suddenly die, it would be better to have gone to confession. We know neither the hour or the place! Let us prepare our bodies and souls as best we can before God takes us out of this world! Repentance means change!
