God's Fourth Commandment bound Old Covenant Israel as a shadow of Christ our true Rest (Colossians 2:16-17). Christ fulfilled it completely-He is Lord of the Sabbath (Matthew 12:8), rose on the first day (the Lord's Day), and grants eternal rest in Himself (Hebrews 4). From the Apostles, Christians gathered for Eucharist on Sunday (Acts 20:7; 1 Corinthians 16:2; Revelation 1:10). The Didache commands: 'On the Lord's Day gather yourselves together and break bread.' St. Ignatius of Antioch (circa 110 AD) in his Epistle to the Magnesians declares Christians 'no longer observing the Sabbath, but living in the observance of the Lord's Day, on which also our life has sprung up again by Him and by His death.'
The Orthodox honor Saturday as the biblical Sabbath: no strict fasting, Vespers prepare for Resurrection, prayers for the dead (Christ rested in the tomb). But the rigid seventh-day observance is rejected as dead letter- the kikes cling to the old creation they rejected by crucifying the Messiah; adventists impose mosaic rules on the New Covenant in ignorance. We live the fulfilled reality: Sunday is the Eighth Day, symbol of new creation, eternal life, Resurrection joy. The true Church has kept this from day one. Legalists judaize and kill the spirit. The spirit must be kept in fullness.

13 Speak thou also unto the children of Israel, saying, Verily my sabbaths ye shall keep: for it is a sign between me and you throughout your generations; that ye may know that I am the LORD that doth sanctify you. 14 Ye shall keep the sabbath therefore; for it is holy unto you: every one that defileth it shall surely be put to death: for whosoever doeth any work therein, that soul shall be cut off from among his people. 15 Six days may work be done; but in the seventh is the sabbath of rest, holy to the LORD: whosoever doeth any work in the sabbath day, he shall surely be put to death. 16 Wherefore the children of Israel shall keep the sabbath, to observe the sabbath throughout their generations, for a perpetual covenant. 17 It is a sign between me and the children of Israel for ever: for in six days the LORD made heaven and earth, and on the seventh day he rested, and was refreshed. Exodus 31:12-17 KJV
