This is an incorrect assumption. The Ecumenical Creeds recorded what the early church believed. If you agree you are not a cult. If you disagree you are a cult.
Sounds like the world CULT is getting mixed with HERETIC.
Cult doesn't even have to be a religion its when you get strong-armed into a system.
The church points out a person is required to follow their good conscience even when it goes against the church. As long as its good not an evil act, or violence. actual GOOD.
If your good conscience requires you to leave you are encourage to follow it. Catholics cannot favor catholics over non-catholics, everyone is equal. If your in family and non-catholic, we are not instructed to hate you, shun you, or kick you out of the family.
Cults will literally command folks to shun the person and if they don't they will share in being shunned.
SDA do employ TERRORISM the same you find even from some denominations here. They use TERRORISM if you are not with us then you are on SATAN's loser side. But if you want to be a winner you must be on my theology and side.
If you worship on sunday.......well then obviously you are a Satan worshipper.
They open up their eyes in ghost story mode, The pope is the devil. His title says 666. Imagine you are hearing this as a child. You are part of the remnant underdogs. the last group of actual GOOD PEOPLE. everyone else serves the devil.
In the JW's they will tell you ALL organizations are SATANIC. Your government, your school, They frown on education and the idea of someone going to college or university is deeply frowned on. Cause of course once you actually learn history, meeting other people, getting thier point of view rather than a vilifying misrepresentation. You start being tolerant of others.
Its always in the interest of evil to keep you as uneducated and stupid as possible. To stay away from history, its part of the Iron Curtain. Or like its said in this thread "IGNORANCE IS BLISS" Lets keep you stupid make sure you don't study up on anything taught.
