The SDA church has explained it simply.
The law of ordinance contained in shadows was abolished at the cross,
And the law of liberty written on stone still stands.
You know this and agree that the shadows were fulfilled at the cross. But you seperate the one comandment we are told to remember and say it is a shadow fulfilled in Christ when Sda's think it is a moral law, like the other 9 written on stone.
2 Corinthians 3:6 - who also made us sufficient as ministers of the
new covenant, not of the letter but of the Spirit; for the letter kills, but the Spirit gives life. 7 But if the
ministry of death, written and engraved on stones, was glorious, so that the children of Israel could not look steadily at the face of Moses because of the glory of his countenance, which glory was passing away, 8 how will the ministry of the Spirit not be more glorious? 9 For if the ministry of condemnation had glory, the ministry of righteousness exceeds much more in glory.
Since the old covenant has been made obsolete, does this leave us with no moral direction? Absolutely not. God made obsolete the old covenant to put into place the new covenant (2 Corinthians 3:6-9; Hebrews 8:6-13). The life of discipleship flows out of the new command, to love one another as He loved us (John 13:34), which Paul refers to as the "law of Christ" (Galatians 6:2). Love fulfills the law (Romans 13:8-10). Out of this command comes other commands, including references for the moral aspect of 9 of the 10 commandments, which are reiterated under the new covenant,
yet the command to keep the Sabbath day is not binding on Christians under the new covenant. It’s not an eternal moral law for Christians.
