It is very important for you to do the Deprogramming from Christianity, if you really want to pursue Zevism for real.
You need to face a lot of your fears, nightmares might appear, doubts will make you want to return to Christianity.
Keep on studying Zevism, the more you study, the more you know what to do.
Put your trust towards the Gods, seek help from Zeus whenever you feel desperate, and be brave enough to endure the hardest moments.
Aura cleaning, and Aura of Protection is extremely important.
Void meditation, awareness, have control of your own mind.
It isn't uncommon to be surrounded by christians, depending on your country and family it is the "normal". Zevists are still quite rare in the world.
The Gods understand that you love your family, even if they are christians. It is not an easy task to convert them to Zevism either.
Some members try and succeed, others decide to stay apart from their family, because of extremely toxic behavior.
How much you can tolerate them or not, that depends on what type of christians are surrounding you.
If they are the more aggressive (and paranoid) types, it would be best for you to keep a distance from them. These "friends" are likely to become "enemies" later, sadly. These ones are the types that harass spiritually (by praying for you, doing vigils at the mount while fasting). DO NOT display anything related to Zevism close to them (like they listen you vibrating words, you forget a candle in your room). I've learned the hard way at the beginning (I was ignorant and naive), it was very unpleasant, and distasteful. I don't recommend the experience to anyone (★☆☆☆☆).
But, if most of them are the types that barely goes to church and don't bother, there is a chance to stay close to them. Just make some excuses, and see how it goes.
You can pretend that you are with them, while being a Zevist in private.
I also have to wear a 'mask' to pretend that I am part of society. Most of the people in my country (and my family) are christians, and they celebrate their usual holidays. I have to pretend that I celebrate Christmas, but I know that I'm celebrating Yule. Thankfully my parents don't watch movies about Jesus anymore, for many years they stopped caring. My parents never pushed me into religion, actually my other family members that pressed them to push me. In the end it didn't work (it never did).
Even then, during my first months as a Zevist, I had a couple of weird dreams of some entities trying to convince me to abandon Zevism, that Christianity was the "right path". Some even disguised themselves as family members or friends. Since I was reading a lot at that time, educating myself with knowledge, their claims seemed very empty.
The same happened when I was found out by family members. I got caught when my aunt was trying to be a born-again christian (she never was...always was into parties and drinking all night lol). I got dragged into several churches, had to hear the priests preach, and deal with strangers "praying for me" (in the astral plane it sucked, once you start having a cleaner aura the "OCD" kicks in).
While he said loud the passages from the bible, I was able to counter-argument them all in my mind, thanks to what HPS Pythia wrote in several of her sermons (★★★★★).
So it is VERY important to read, study until you know everything at heart, feel that it is a lie, an illusion. Eventually the doubts will go away, and you'll be sure that it was all manipulation for the masses.
