A famous child opera star broke free from her father's grip with newfound unicorn powers but, not used to the real world, ended up using all her money and nearly died on the street before a crazy redhead pegasus aspect picked her up and taught her how to be confident. The red-head's half sister was having a vacation in some eastern countries when she heard about Tirek's reign of terror, and decided to head to Tauros to punch some bad guys with her earth aspect. She found a low-class bookworm griffon aspect, and together they liberated a small section of the town before heading home.
When the sisters met, they introduced their new friends to each other. Tensions rose when it was discovered the child star's father had some dealings with Tirek, but it was agreed that said father was a jackass. Shortly thereafter, Sunset Shimmer showed her video of her original self, the church of the divine bacon horse was formed, and while three of the friends laughed off the new development the redhead was so eager she immediately walked to Sunset's home (which was only three houses away), knocked on the door, and asked to become the pope.
Shortly after being awarded the position (and the resulting paperwork), the redhead wrangled her three friends into helping her to establish a system and order to the whole thing. For a time, they were stressed out and seriously considered abandoning the whole thing, but then an outbreak of a magical disease created angst monsters out of local animals and all four of them (who had combat training for various reasons and had experimented with magic weapons out of boredom) worked together with the members of their church to put the monsters down. After that, they were solidified as bishops in their own right.
All this happened over the course of a month.

Sunset got up when she heard the knock at her door. She opened the door with a smile on her face, though that quickly changed.
"Hi, Sunset!"
"Pinkie."
"Yes?"
Sunset pointed at the device in Pinkie's hands. "What is that thing?"
Pinkie beamed and hefted it up to give Sunset a better look. "It's the Pinkie-portable party cannon! Pee-three-see for short."
"It's a grenade launcher."
"Party bomb launcher." Pinkie put the P3C through a few shifts and clicks. "It's also a hammer!"
Sunset took a deep breath. "Why is it also a hammer?"
"Piñatas."
After taking in the war hammer that any minotaur would've been proud to call his own, Sunset said, "You've been talking to Ruby again, haven't you?"
Twilight looked up from her book. "I told you first come, first served was no way to determine a religious hierarchy."
