Ba'zi e'tiqod tizimlari o'z mohiyatiga ko'ra ruhiydir. Bu shuni anglatadiki, ular faqat olamning yaratuvchisi yoki boshqaruvchisi haqidagi tushuncha bilan bog'liq bo'lib, faqat shaxslarning o'sha yaratuvchi bilan munosabatini yoritadi. Buning misoli Buddaviylik bo'lib, unda jamiyat va hayot ishlarini tashkil etishdan ko'ra ruhiyatga urg'u beriladi. Shunday ekan, Buddaviylikni ruhiy 'aqida deb atash mumkin. Boshqa e'tiqodlar esa butunlay siyosiydir. Masalan, kommunizmda yaratuvchining mavjudligi inkor etiladi, shuning uchun uning e'tiqodi shaxsning yaratuvchi bilan munosabati masalasini ko'tarmaydi. Biroq kommunizm insonlarning ishlari bilan shug'ullanadi va ular hayotlarini qanday tashkil etishlari kerakligi haqida qoidalar belgilaydi, ayniqsa iqtisodiy jihatga oid. Shunday ekan, kommunizm siyosiy 'aqida hisoblanadi.

Some belief systems are by their nature spiritual. By this, it is meant that they relate only to the cogniscance of a creator or organiser of the universe, and they address only the relationship of individuals to that creator. An example of this is Buddhism, where emphasis is laid upon spiritualty, rather than organisation of society and lifes affairs. Thus, Buddhism can be called a spiritual ‘aqeedah. Other creeds are entirely political. For example, in Communism, the existence of a creator is denied, and its belief therefore does not raise the issue of the relationship of the individual with a creator. However, Communism addresses the affairs of human beings, and it lays down rules regarding how they should organise their lives, particularly in reference to the economic aspect. Thus, Communism is a political ‘aqeedah.
