I would simply ask why they are offended so you could get a better idea of why it offends them. I would also stay away from the word denomination too.
I second this. Also, Christians are not just ‘simply Christians’. Ask the average Baptist, evangelical, or ‘Bible Christian’ if he thinks his Christianity is just like that of a Catholic or an Orthodox Christian.
I venture to say the average person of a non-Catholic, non-Orthodox Christian faith view would not consider his/her Christian faith as ‘equivalent’ to the Catholic Christian in the way that he/she would consider it such in comparison to another non-Catholic non-Orthodox Christian faith view. In fact, while very few of them would have too much to say ‘against’ another non-Catholic Christian view, they would have a LOT to say in opposition to the Catholic/Orthodox Christian views.
If they do not wish to be called Protestants with the idea that there are too many differences among individual Protestant groups, that is one thing, but they aren’t just ‘simply Christians’ because that term is entirely too broad. Like it or not, in their own best interest, they need to be more specific in order that we can ‘meet them’ properly.
Suppose they are ‘just Christians’ who happen to be Seventh Day Adventist. Well, if we call them ‘just Christians’ we’re probably going to offend them if we ask to join them at church on Sunday (the day that just about every other ‘just Christian’ attends Church). However, if we call them not Protestant but “Seventh Day Adventist” then we’re going to be able to ‘meet them’ by focusing on something that ‘all Christians’ have in common, instead of focusing on something that that one particular group does NOT have in common with other ‘just Christians’.
What if they are just Christians who happen to be a small non denom group that practices absolute Bible literalism (women wear only dresses, men are the ‘heads of household’, etc.); well, we probably would try to at least not ASK WHY the women are wearing dresses when all the other women around them are wearing pants, which MOST ‘just Christian’ women do), and we probably wouldn’t get into discussions about the role of feminism in Christianity from the get go, but instead focus on other Christian teachings we have in common.
A person who is ‘just Christian’ can be:
One who believes in infant baptism.
One who does NOT believe in infant baptism.
One who believes in bible literalism.
One who does NOT believe in bible literalism.
One who believes in the real presence in the Eucharist.
One who does NOT believe in the real presence in the Eucharist.
One who believes in seven sacraments.
One who believes in two sacraments.
One who believes in no sacraments.
One who has a hierarchy of priests.
One who has no hierarchy at all.
One with a very formal ritual liturgy.
One with a very informal liturgy.
One who believes in remarriage after divorce.
One who does not believe in remarriage after divorce.
One who supports female ordination.
One who does not support female ordination. .
JUST Christian? I’ve only barely touched on many aspects of dissimilar belief in Christian faith teachings. . . which ‘just Christian’ parts apply to the people in question, and how many other beliefs do they have which other ‘just Christians’ do not, I wonder?
