Hi,
I do believe God can and will send other prophets after EGW to His endtime church. But I have never heard of Jeanine Sautron.
I assume if Jeanine Sautron claims to be a prophet from God, she would not contradict the previous prophet sent from God.
Here EGW testifed on what constitute Babylon.
The wine of Babylon is the exalting of the false and spurious sabbath above the Sabbath which the Lord Jehovah hath blessed and sanctified for the use of man, also [it is] the immortality of the soul. These kindred heresies, and the rejection of the truth, convert the church into Babylon. Kings, merchants, rulers, and religious teachers are all in corrupt harmony. {2SM 68.2}
"It is our individual duty to walk humbly with God. We are not to seek any strange, new message. We are not to think that the chosen ones of God who are trying to walk in the light compose Babylon. The fallen denominational churches are Babylon. Babylon has been fostering poisonous doctrines, the wine of error. This wine of error is made up of false doctrines, such as the natural immortality of the soul, the eternal torment of the wicked, the denial of the pre-existence of Christ prior to His birth in Bethlehem, and advocating and exalting the first day of the week above God's holy and sanctified day. These and kindred errors are presented to the world by the various churches, and thus the Scriptures are fulfilled that say, 'For all nations have drunk of the wine of the wrath of her fornication.' It is a wrath which is created by false doctrines, and when kings and presidents drink this wine of the wrath of her fornication, they are stirred with anger against those who will not come into harmony with the false and satanic heresies which exalt the false sabbath, and lead men to trample underfoot God's memorial. {TM 61.3}
It is the false teaching of the spurious sabbath and the immortality of the soul that constitute Babylon. The SDA church has backslid and apostatized. The church structure is infiltrated and corrupted. No question. They are all well documented.
But the SDA church has not officially taught these two fables of the wine of Babylon. EGW wrote that there had never been a message from God to leave the SDA church in her time. I'm persuaded to think there will never be such a message until the church officially teaches those two false doctrines.
Another problem I see is that when new people come into the SDA church, if there is no servant of God remaining who still bear the true light, they will be thrown to the wolves and stand a little chance.
The Philadelphians will go through the Laodiceans to the end, because the Philadelphians will witness to the Laodiceans and made known to them that God has loved the Philadelphians.
