I have no belief about that claim.
Their doctrines of salvation I agree with largely. They later joined with the Reformation, being so similar.
They were founded in the 12th century, proving your claim not true, that these beliefs only began 1500 years after Christ.
Nice try moving the goalpost though 😊
Waldensians held and preached a number of truths as they read from the Bible. These included:The atoning death and justifying righteousness of Christ
The Godhead
The fall of man
The incarnation of the Son
A denial of purgatory as the "invention of the Antichrist"[11]
The value of voluntary poverty
They also rejected a number of concepts that were widely held in Christian Europe of the era.For example, the Waldensians held that temporal offices and dignities were not meant for preachers of the Gospel; that relics were simply bones that should not be regarded as special or holy; that pilgrimage served only to spend one's money; that flesh might be eaten any day if one's appetite served one; that holy water was not a whit more efficacious than rain water; and that prayer in a barn was just as effectual as if offered in a church.
They were accused, moreover, of having scoffed at the doctrine of transubstantiation, and of having spoken blasphemously of the Catholic Church as the harlot of the Apocalypse.[12] They rejected what they perceived as the idolatry of the Catholic Church and considered the Papacy as the Antichrist of Rome.[13]
