No. Jehovah Witnesses are though.
Witnesses, Seventh Day Adventists, Dispensationalists, Mormons - all of these are 19th century modernist philosophies that arose in the USA.
In the Bible the word “dispensation” never refers to a period of time. Invariably its meaning is “a stewardship,” “the act of dispensing,” “an administration.” Read the four New Testament texts in which the word “dispensation” is found: 1 Corinthians 9:17; Ephesians 1:10; 3:2; and Colossians 1:25. Weymouth’s translation of 1 Corinthians 9:17 reads: “A stewardship has nevertheless been entrusted to me.”
The plan of the ages is a gospel plan. God’s dealings with man have been ever the same. Faithful Abel and Enoch, Abraham and Moses, were all “saved by grace.” Their lives were marked by obedience to God’s commandments. By “faith,” they obeyed So, today God’s remnant church is a church which keeps the commandments of God and the faith of Jesus.
