Christ Rose on the Sabbath--strongest proof-text, 1Corinthians 15:17, "If Christ be not raised, your faith is vain, ye are yet in your sins." "If Christ ROSE not from the dead, you still are IN YOUR SINS!" even though ~keeping the Sabbath~ as a righteous work OF THE LAW and not as "Sabbaths' Feast OF CHRIST the Substance”. For “JESUS gave them (the People of God) REST ... as "CHRIST ROSE from the dead" … having entered into His Own Rest as God in His Own", “and God on the day The Seventh Day (Sabbath OF THE LORD GOD) from all his works RESTED ... and REVIVED”. For "CHRIST ROSE from the dead", "having been Rested-up-again His Name being The Most Holy Place" of God's Sanctuary, haven in the Peace and Rest of God's Fullness.
