"Next in importance to freedom and justice is popular education, without which neither justice nor freedom can be permanently maintained. Its interests are intrusted to the States and the voluntary action of the people. Whatever help the nation can justly afford should be generously given to aid the States in supporting common schools; but it would be unjust to our people and dangerous to our institutions to apply any portion of the revenues of the nation or of the States to the support of sectarian schools. The separation of Church and State in everything relating to taxation should be absolute."
