How do I (17M) tell our youth leader that I'm an agnostic and that I won't be part of the music team?

As the title suggests, I’m an agnostic—meaning that whether or not God exists, He/She/It cannot be fully proven. To me, it makes sense that science neither proves nor disproves God or the supernatural. So while I’m agnostic regarding the general concept of God, I’m essentially an atheist when it comes to Christianity.

That said, I don’t hold extreme views about Christianity. I don’t think Christians are delusional for believing in God, nor do I see Christianity as inherently oppressive. My doubts aren’t personal; they’re more about the epistemology of belief (which I’ll explain in the comments).

My Background and Faith Journey

I’ve been in an evangelical church my whole life 17 years now. When I was around 13-14, I genuinely sought God on a deeper level because I didn’t want to be just another passive, lukewarm Christian. I wanted to carry my cross daily, deny myself, resist worldly desires, deepen my theological knowledge, and try my best to devote my life to Christ. (I also watched a lot of John Piper and Christian commentary).

However, as I explored my faith intellectually, doubts emerged. At 14, I leaned toward Catholicism I remember crying while praying to God about how much Catholicism made sense and how my life up to that point felt like a lie. I even planned to get baptized in the Catholic Church even if my parents are againt it. But after months of watching countless debates, reading articles, and engaging in online discussions, I eventually concluded that Christianity, in general, isn’t true. That realization didn’t hit me as hard as my shift from evangelicalism to Catholicism probably because the first domino was the one that mattered the most because I couldn't believe that it made so much sense.

So My family has been part of this church for two decades (they were formerly Catholics), and I grew up there. People see me as a devoted Christian, and I genuinely like the people there—they’re nice and not particularly judgmental. So I’ve never had a "Man, these Christians are hypocrites" type of experience.

My Youth Leader and the Dilemma

My youth leader, Chris, is about 28-29 he's been a youth leader (not a pastor) since he was 21 (I'll explain it much later). I’ve known him for around 10 months, and 1-2 times a month during fridays, he, my close friend (who’s 16), and I go out for a Bible study (though only if my friend goes too) but I don't feel any discomfort with Chris at all except when I have to talk about my experience with God which I don't have so I just vaguely talk about it the same way I would explain it when I was 13-14 (which only happens during fridays). Honestly we just talk about random stuff after during sundays. And one thing I should mention is that there aren’t that many guys our age who regularly attend church just about five of us so my participation in the church means a lot.

So, Chris is an easygoing guy and is nice, but I don’t want to burst the bubble that I’ve actually been an atheist-agnostic for the past two years. He used to live a rough life, he was deep into drugs, involved in street fights, and hit rock bottom when he overdosed. At his lowest point, he prayed to God as a last resort and felt a renewed sense of purpose, which led him back to faith. I think that’s a beautiful transformation for anyone.

Naturally, he has a lot of assumptions about why Christians leave the faith. Once, he talked about a Hillsong songwriter who became an atheist, and I could feel the disappointment and disgust in his tone. However, he also mentioned that, like Samson, God still used that person in his younger years to write Christian music. That’s probably the most judgmental I’ve seen him be—otherwise, he’s easygoing.

Now, here’s the issue**:** I don’t know if I should tell him I can’t be the lead guitarist for the church’s music team. For the past two months, both Chris and my friend have been hyping me up for the role (my friend plays rhythm guitar), and because I’m too much of a people pleaser, I signed up last Sunday.

They’re not forcing me, but I feel like the pressure has been building because I haven’t been upfront about my beliefs. Now I’m stuck. This is my lowest point (exaggeration) but it's still a tough situation for me.

So what do I do?
