Sabbaton appears 68 times in the NT. It is a transliteration of the Hebrew shabbāt (H7676), 'rest, cessation,' from the verb shābat, 'to cease, rest.' The Sabbath was instituted at creation (Genesis 2:2-3), embedded in the fourth commandment (Exodus 20:8-11), and observed by Israel as a weekly sign of the covenant (Exodus 31:12-17). In the NT, Jesus regularly taught in synagogues on the Sabbath and performed healings on that day, generating significant controversy with religious leaders over what constituted 'Sabbath-keeping.'
Jesus's Sabbath healings were not violations of the Sabbath — they were demonstrations of its true meaning. 'The Sabbath was made for man, not man for the Sabbath' (Mark 2:27). Jesus as 'Lord of the Sabbath' (Mark 2:28) is the authoritative interpreter of the day's purpose: restoration, liberation, and freedom — the very things his healings enacted. The early church shifted primary worship to 'the first day of the week' (mia tōn sabbatōn, literally 'one of the Sabbaths') in commemoration of the resurrection (Acts 20:7; 1 Corinthians 16:2). Hebrews 4 speaks of a coming 'Sabbath rest' (sabbatismos) for God's people — the eschatological rest that Christ's completed work makes possible.
