"Traditional Christianity turns the 'Law' on its head and makes obedience to G-d's loving instructions to be something bad, and the rejection of His instructions to be something good."
Can we say, for the sake of discussion, that there are two entities descended from Judaism: Christianity and Christendom. Let us define Christendom as that group often referred to as "Traditional Christianity" making Christianity the group who follow the Way, as in, "I am the Way the Truth and the Life; no man comes to the Father but by me."
In Isaiah 62:11 it is written: Behold, the LORD hath proclaimed Unto the end of the earth: Say ye to the daughter of Zion: "Behold, thy salvation cometh; Behold, His reward is with Him." What is the Hebrew word translated salvation? Do the pronouns His and Him refer back to the salvation which cometh? Why do you think that Christianity does not believe this verse?
Yeshua haMashiach was asked: "What is the great commandment?" He answered: "You shall love the LORD your God with all your heart, and with all your soul, and with all your mind. This is the great and foremost commandment. The second is like it, "You shall love your neighbor as yourself. On these two commandments depend the whole Law and the Prophets." As the Law was important to Him, so it is important to those who follow Him. So, though Christendom may "turn the Law on its head" Christianity seeks to know the Law as it appears in the Tanakh. We wish to know the words of the prophets, so that we may know the will of HaShem.
When I ask questions, no matter how impertinent they seem, it is to make all of us think. Only by keeping the Word in our minds and our hearts can we ever hope to know what the Creator and Father of us all would that we do to glorify Him. I am a believer who follows the Way. And I believe that the Sabbath begins as the sun sets on Friday evening and the First day begins at the same hour on Saturday. Neither of us should look down upon the other for keeping or not keeping either day.
May He who neither slumbers nor sleeps hold you in the palm of His hand. May you one day wake to see Him face to face.
He answered: "You shall love the LORD your God with all your heart.."
IMO, you left out the MOST important part he stated.. that is, "Hear O Isreal, the Lord is one" That concept is the very center teaching of all of the scriptures, and the rest of the statement is empty without it.
