According to each of their own "statements of Faith" they actually do contradict each other in big issues. before I lay it out, however, here are my citations:
The first issue on which they contradict each other is purgatory. Waldensians say there is no purgatory. They say people will go either two ways “(the) good to glory, wicked to torment” which leaves room for purgatory, but then later in their statement they say “For you shall be damned without remedy.” No purgatorial redemption.
They Lollards say that yes, there is purgatory. “(acts)...will have needful purgation or worse.”
The next issue is celibacy. the Waldensians say "That he might likewise keep firm the marriage tie, that noble accord and contract."
In the issue of celibacy, the Lollards say yes, do participate in celibacy.
And the last difference I will talk about is Confession (to priests). Waldensians say "Then he desires the Priest to confess him:
But according to the Scriptures he has delayed too long, for that commands us
To repent while we have time, and not to put it off till the last." They then go on expound on this topic.
The Lollards, however, say confession is necessary to the salvation of man.
Lollards and Waldensians contradict each other in purgatory, celibacy, and confession. Some say that one's view of purgatory and confession will, either positively or negatively, affect their eternal destiny.
