it's not stealing - it's we learn from each other and grow in the faith.
The 19th century and the radical reformation had a lot of changes.
If I look at it with a historians hat you have
- The collapse of the giant Asian powers - the Maratha Confederation in India and the Qing Empire
- The industrial revolution
- England, France and the Netherlands rising beyond just thalassocracies
- The rise of "scientific criticism" of the Bible
- Evolution
- The implementation of evolution as a concept to create racism and also "religion progression"
During this time you have the Adventists, the Jehovah's witnesses, the Evangelicals, the Mormons, the concept of the rapture etc. all arising and influenced by those secular changes
