Eternal sin
Thomas Aquinas lists, or has responded to, six sins that supposedly go against the Holy Spirit:
Thomas Aquinas explains that the unforgivability of blasphemy against the Holy Spirit means that it removes the entrance to these means of salvation; however, it cannot hinder God in taking away this obstacle by way of a miracle.
Christian theology
The Greek word in the New Testament that is translated in English as "sin" is "hamartia", which literally means "missing the target". 1 John 3:4 states: "Everyone who sins breaks the law; in fact, sin is lawlessness". Jesus clarified the law by defining its foundation: "Jesus replied: 'Love the Lord your God with all your heart and with all your soul and with all your mind.' This is the first and greatest commandment. And the second is like it: 'Love your neighbor as yourself.' All the Law and the Prophets hang on these two commandments." ()
