Thomas Jefferson and the USA Constitution
His conviction was that religion was a very personal matter, one with which the government had no business getting involved.
He was vilified by his political opponents for his role in the passage of the 1786 Virginia Statute for Religious Freedom.
As the author of the Virginia Statute for Religious Freedom, which prohibited government interference in people’s religious beliefs, Jefferson took a hard line in this regard, and it isn’t difficult to imagine where he would stand on current debates about prayer in public schools, say, or faith-based funding for social projects.
If there is one field of constitutional law, and law generally, where Jefferson was amazing, it’s the separation of church and state. He thought the alliance of religion and government corrupted both, and that that endangered the liberty of the individual mind.
