It is very beautiful and interesting to me that Stoics and Buddhists arrived at very similar conclusions despite being thousands of miles apart and having little to no contact.
Speaking for myself, another reason I enjoy Buddhism and Stoicism is that they feel more like pure, distilled wisdom. Especially Zen Buddhism. Christian writings are filled with excessive moralizing and mythology, which enables all sorts of problems.

While there isn't much direct evidence to support this theory, both philosophies have some ideas related to mindfulness that are too similar to me to be a coincidence.

Unfortunately Christianity suffers from excessive moralizing and mythology, which turns me away from it. But it definitely has lines of thought that descended from stoic thinking.
