Aziraphale strolled through the rows of church benches all the way to the altar. Churches had become a place of salvation in these dark times. People seeked refugee in them, but the angel wasn't here to save humans. This time his mission was solely to deliver some rare books to a foreign client. But the truth was that he worked undercover, as a double agent he could say, to bust some german officials. The scenario unfolded but not quite as planned. In the end he got rescued by Crowley. The poor demon got quite the burn on his footsoles from the holy ground, but that never seemed to bothered him. That was at least what the angel thought.

Timeskip

The two beings used their time with their favourite passtime. Being drunk. In this condition they talked about everything, until they began to follow down memory lane to the day in the church during 2. WW.
While the angel wanted to hug his friend to take away his pain and sorrow (now after the Apocawasnt he finally dared), the demon came up with the craziest ideas to avoid the holy burn.
One stuck especially. Even after sobering up he still had to think about it. So he let the intrusive thoughts win and bought some Rollerblades. The plan was simple. He would wear them to a church and because of the rolles he wouldn't be touching the ground. This should result in not getting burned.

As thought so done... Taking a deep breath he threw the doors open and slided in.
He was so nervous that he only realised at the middle of the chruch that his feet didn't hurt.
Halleluja! It worked!
Driving through the whole building he thought of the happiness he would see in the angels eyes. He could go with him from now on and even better he could go all by himself. Being in a church felt hurtfull but heavenly at the same time. It felt like a painful lost memory that tried to resurface.
Rolling the last meters to the altar Crowley stopped. His gaze shifted from his blades to the glasswindow above the altar. Why? He didn't understand the Almighty.
But he didn't care what reason there was for such loopholes, he was just grateful that they existed and that he was creative enough to find them.
Maybe there was a reason, a big plan behind it all and maybe not. Either way he would follow his own path. Neither heavenly nor hellish but human, with all the nifty things they created to make his eternity better.
