“Are protestants true Christians? A simple ‘yes’ or ‘no’ will do.”
Since Protestantism comes in multiple flavors, that can’t be answered with a blanket yes or no. The best I can give you is, most are, some are not.
Same is true for adherents of any religious affiliation. Some are true, some are just wearing the label. I think, tbpiper, you may be asking about theology, not persons.
**The best I can give you is, most are, some are not.**
That’s an opinion based on what, or who? You’re making a judgement without naming names or qualifications. You need to finish your judgement,.....if you can.
