The First Amendment Religion Clause: “Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof…” This book takes an in-depth look at the religion clause portion of the First Amendment using historical documents and letters. In chapter one examples are given of the historical reasons for why the Framers of the First Amendment (the Founding Fathers) thought it was necessary to list religion as part of the Bill of Rights in the manner that they did. In chapter two documentation is presented showing how they applied it during their times of service in government. The application of the 14th Amendment is examined along with whether or not it should be applied to the 1st Amendment based on the history of both. In chapter three a complete analysis is made of Thomas Jefferson’s “wall of separation” letter, and in chapter four an in-depth investigation is taken into Jefferson’s Virginian Act for Establishing Religious Freedom, James Madison’s Memorial and Remonstrance Against Religious Assessments, and Madison’s Detached Memoranda essay on religion and government interaction. These documents, along with others examined in this book, display the Founding Fathers’ views as to why there is a religious clause, and what its proper application should be between church (that is, religion) and state. This book also contains present day solutions for how the government could act legally and constitutionally regarding religion (and related religious books) and toward those who claim religious reasons as their motivation to physically harm others. History reveals the continued purpose and need for the Religion Clause in the Bill of Rights.
