Below is a list of the proposed Changes in doctrine of the SDA Church by The SEA movement.
1. Christ ruling in Jerusalem for 1000 years. Isa 66:23, Rev 15:4, Ps 86:9, Rev 20:4,6
2. The sabbath as a sign and prediction of the 1000 years regin. Isa 66:23, Heb 4:9-11
3. Sunday, as mark of the beast, for trying to set up the kingdom of God on earth and not waiting for Jesus to come and rule from Jerusalem for 1000 years.
4. 666 pointing to Solomon , A type of Christ and Anti-Christ, making a compermise with the world. 1 Kings 10:4, 2 Chron 9:13.
5. The pre-fall nature of Christ. To be fair most of Mainline SDA Church believes this. it is only those that support EGW that believe Jesus had a post fall nature.
6. Soul Sleep - there is a Body, Soul & Spirit and upon death, the Spirit return to God, the Body return to the dust and the Soul goes to Sheol, the Chamber of Darkness and is a sleep. This is in the O.T. After Christ come a Modification take places. if a person accepts Christ, then the Soul & Spirit will go to heaven for the believer, and the body to the grave. the soul and spirit are reunited with the body at the Advent, when the saints are taken to the marriage supper of the lamb (1Thess. 4:13,14). For the Unbeliever it is the same as the OT.
7. The Advent happens before the tribulation, where the faithful saints are taken out of this world to the Marriage supper of the Lamb and return at the beginning of the 1000 years.
8. The unfaithful saints must go through the tribulation and are part of the 144000 & The Great multitude that no man can number. Rev 7:4, Rev 14:1,3, Ezra 2:13, Rev 13:18, 1Kings 10:14, 2Chron 9:13
9. changes to the view of the Sabbath to Sunday.
1. Sabbath was kept changed for over 300 years until the time of Constintine, then due to politics , the Holiness of the Day was transferred to the first day of the Week or the Lords's day. it was now a sign of loyality to the State. Sabbath was eventually banned due to defection during a time of persecution. It became "anathama" to observe sabbath.
2. The Lord's Day - was established by the Apostles. it was based on the Resurrection, the post ressurecction of Jesus and Jesus Fulfilling the Festivals: Palm Sunday(Lamb selection Sunday) Resurrection Sunday(First Fruits) & Holy Spirit Sunday (Pentacost). All on the first day of the week. It was an ADDITION to the Sabbath observance not a Replacement. It was Observed as a Festival, NOT a Sabbath, NOT a day of no work, until the time of Constantine. Due to politics, Sylverter I the bishop of Rome transfered the Holiness of Sabbath to the Lord's day. Eventually due to politics the Lord's day usurped the Sabbath and then replaced it.
