Did the constitution guarantee freedom of religion?

Under the First Amendment of the United States Constitution, it states that a person cannot "prohibit the free exercise of religion." Hence, a person cannot infringe on a person's right to practice their own preference of religion. The first Amendment says, "CONGRESS SHALL MAKE NO LAWS RESPECTING AN ESTABLISHMENT OF RELIGION". That simply means to keep your belief in your church, home and in your own hearts. Not in everyone else's faces.
