Advice on Caught Katibayan Forgery

I have been caught sending fake Katibayans because my name wasn’t on their logbook (which is true), and now they are pinning me down because they think it is an awful sin or, for them, a crime.

My friend said that a manggagawa will visit me to talk (which is only gaslighting) and explain why I did such an act. My friend also said that I will write a salaysay addressed to Manalo, which I don’t believe he will receive.

Now, I’m so confused. Should I just write the letter and seal it? And if the manggagawa reads the contents, I might actually stop attending church. Or should I still talk with the manggagawa and still write a letter?

For context, my dad is a deacon and also a katiwala of the family. I stopped attending church because our mom died, and I lost my faith because of all the things they were saying.

Should I just lie about it? Or should I say what they want to hear?
