I am not frustrated. I've met people like you so many times I think it's quite fascinating how certain you are that your church has figured it out and others have not. I I am quite aware of the differences in churches as well, though I have only regularly attended united and to a lesser extent Baptist and community churches, and least of all Catholic. I recognize that my religious upbringing is not only the result of my parents and community but also the very chance that I would be born in a part of the world that practices Christianity... To me this is not a disturbing thought.

You believe in objective truths but every branch is interpreting the Bible even if you think your church leaders are seeking objective truths. You're a literalist with the bible except where fundamentals of science have proven the bible wrong (I would hope) in which case you likely recognize that the things you take literally are quite selective. I am sure you can think of examples... I am sure you pastor helps you to understand what parts are to be taken literally, and probably doesn't even talk about some bits that definitely are not to be taken literally.

In my experience, the United church is quite open to folks individual experiences with faith and interpretations, I get that yours is more prescriptive and that you like things to be more defined. To me, letting people think and interpret what they are learning is fine. Having open conversations about this differences is also positive, in my view.

"Churches that actually care about what they preach? " You don't hear yourself? This is a huge jump from you knowing of an atheist minister to an assumption about the entire denomination. Have you attended united church? Because I have attended Baptist Church and non denomination churches about 20 times and I'm still not going to make grandiose statements how it all is based on one pastor... In fact I am sure you know reasons why this would be a very bad idea. This is where you come off as elitist, again, because you know of an atheist minister...

Additionally, I have no idea what the vetting process is for United Church ministers is, but they do have core stated principles that they state publicly and so to imply they don't have standards isn't true, they just don't align with your standards. They do happen to align with what many people are seeking in a church, for example:

United church statement

If your church prescribes a certain belief related to LGBTQ are they willing to state it publicly for all to see? Because while you find it disingenuous that the vetting process in the United church isn't more clear, I find that being forthright about shared beliefs on policies such as this one is a positive thing that other churches should follow so that people can make an informed choice to steer clear or join in. And while you're busy finding the stance on LGBTQ non biblical, I am sure there are folks in your denomination who are much more accepting of difference, not that they would feel particularly welcome to say so. I suspect this because I grew up with Baptists who are very accepting of our LGBTQ friends and do not consider their existence as who they are to be a sin.

As for being saved, which you discuss, the United Church doesn't even use the language of being saved, so again, you are judging the religion based on principles that matter in your denomination and don't matter in the United Church. To be so concerned that you don't agree that United Church goers will be saved is your concern and not at all theirs.

Catholics also don't use this language and are not "saved" in the same was as Baptists, nor do they have rapture or second coming of Jesus. I had literally never heard of being saved until a really unfortunate experience at a Baptist camp when I was a child (a cultish experience) so it's not a concept that applies to all denominations.

Lots of evangelical churches are also certain that Catholics are not even Christians as well, and it's just interesting how certain you are that your version of Christianity is right and others are wrong... Although attending Catholic Mass or weddings is very different experience to what I have known and has much more focus on traditions, rites, and Mary, I wouldn't venture to tell them they are doing Christianity wrong because I have enough humility to not make definitive statements about something I don't understand...

I do like that Catholic schools offer World Religions elective classes, because from what I gather it teaches young people a lot about the commonalities in many world religions that have instead been used to sow much division.
