What is the difference between original sin and original guilt?

This is a question that every convert to Eastern Orthodoxy always asked. The question can be stated differently: [Does the Catholic doctrine of Original Sin include Original Guilt?](http://taylormarshall.com/2011/07/does-original-sin-guilty-babies.html) Fr. John Romanides famously distinguish Ancestral Sin from St. Augustine's Original Sin, claiming the later was erroneously introducing Manichaean view of Original Guilt into Latin theology. [Fr. Vladimir Moss](http://www.orthodoxchristianbooks.com/articles/399/romanides-original-sin/) wrote extensively to show why the doctrine of Original Sin is Apostolic in origin and dogmatically sound in Orthodoxy. To further clarify [why original sin and ancestral sin are not substantially different?](https://christianity.stackexchange.com/questions/4814/how-do-the-catholic-and-orthodox-views-of-original-sin-differ/37431#37431) It's important to address what is the difference between Original Sin and later theological development from Protestant on Original Guilt?
