To those who distort the Sabbath day observed by Jesus-God the Father& God the Mother

Today, there are people who call themselves "Orthodox" while worshiping on Sunday which is not based on the Bible and distorting the truth by claiming that "Jesus did not keep the Sabbath day" with regard to the verse indicating that Jesus observed the Sabbath day. Yet, they overlook one thing: if they misinterpret the verse regarding the Sabbath day kept by Jesus as "Jesus did not keep the Sabbath", they lose the slightest opportunity to justify the "Sunday service" they observe. 

First, let's see the verse about the Sabbath day observed by Jesus.

He went to Nazareth, where he had been brought up, and on the Sabbath day he went into the synagogue, as was his custom. And he stood up to read. (Luke 4:16)

About the above Verse, they distort the truth by saying: "At first glance, it seems that Jesus kept the Sabbath day. However, if you read it carefully once more, you will find that there is no word "observe." The Bible says, "On the Sabbath day, Jesus went into the synagogue to read the Bible." Can we understand it today as ‘Jesus observed the Sabbath day?’”

They insist that it's not about keeping the Sabbath day since there is no direct expression "observe". Then, let's apply their logic to the Sunday service the same way. Are there any verses indicating Jesus kept the Sunday service?  At least, are they any record that Jesus went into the synagogue to read the Bible? They must first provide the ground for the Sunday service before they argue about the Sabbath day. They distort the truth by claiming that the Sabbath day was not observed although there is a record of keeping the Sabbath day. I wonder on what ground they keep the Sunday service. Isn’t it strange?

The word "custom" is the translation of the Greek word "ἔθω (εἰωθὸς)", which means "custom, common practice or ritual." In other words, we can confirm that the Sabbath day is a day observed as a custom, common practice or ritual. Of course, since the Sabbath day is one of God's Commandments, it can be also called "as his custom was or as he did as usual." It's because observed the Sabbath day as his custom was or as he did as usual.

Why do they diligently keep the Sunday service which was not kept by Jesus without considering observing the Sabbath day kept by Jesus? Believing in God with lips only; the demons also do. The demons also believe in God (James 2:19), the demons also acknowledged Jesus as the Lord (Matthew 8:29), and even the evil spirit said he knew Jesus (Acts 19:15.) If we get salvation as long as we believe without action, it can be also said that the demons and evil spirits who are destined to be destroyed will be saved. The difference between the devils who are destined to be destroyed and the Christians who will be saved depends on whether or not to do according to the words of God.
