If one followed the ten comandments to the letter would he not be following all the written Torah?
The Greatest Commandment
Matt 22:34 Hearing that Jesus had silenced the Sadducees, the Pharisees got together. 35 One of them, an expert in the law, tested him with this question: 36 Teacher, which is the greatest commandment in the Law?
37 Jesus replied: Love the Lord your God with all your heart and with all your soul and with all your mind.[c] 38 This is the first and greatest commandment. 39 And the second is like it: Love your neighbor as yourself.[d] 40 All the Law and the Prophets hang on these two commandments.
