The axiomatic system of faith that I choose to believe in is the dogma of the Orthodox Catholic Church, as it was established in the First Ecumenical Council of Nicaea.
This for most people who know me personally oftentimes comes as a surprise, especially to those that know me from a young age, during which I was an atheist; I rejected the axiomatic system I currently believe in, and I followed the system of "pure scientific truth", ignoring the gaps and weaknesses it presents.
The first cracks in my absolute devotion to science occurred during my first years in university, when I came into contact with friends which I will forever hold dear to my heart, as well as with various psychedelic substances, both of which caused me to reevaluate the relationship between faith and science. The substances, psylocybin, lysergic acid diethylamide, and 2C-B, (in this order) created in me, or rather, forced me to demolish the idea of absoluteness of reality and of the nature of truth, and start from the beginning.
Through the above, I became exposed to new ideas, new means by which humans have interpreted nature throughout the millenia of human experience, and for years I delved into the different religions of humanity, as well as the philosophical ideas that rise from them.
These journeys, mental and physical, led me to many questions which no religion, philosophy, or axiomatic system could answer, except for the one I believe in now.
The fact that God is, rather than not, and specifically as he is described in the Orthodox dogma, is a necessity for the system of reality, as I see it and understand it, to be self-consistent. Not only does it close the gaps that are left open by other axiomatic systems, but also eclipses and explains why these other systems occur.
Assuming someone knows, or is near to, the Truth, and modifies it, by removing sections, or by adding new ones, then they are able to create every "truthfull" system we have discovered as humans. As a result of these modifications though, it is impossible to trace back the original Truth, without the Truth itself, and the modifications and the modifiers become lost in history.
After all, the best lie is that which wholly contains the Truth, except for a single point, a detail that nobody can recognize as false, without first knowing the Truth.
