Celtic tradition is still alive among so many and getting more and more popular with time include all elements of true faith, which we missed today.
Let's look at a few principals of this strong believe system. Celtic followers believe in equality of man and women. They love music, poetry and art, and are close to nature and God's creatures. Personal sanctity is more important for them then the doctrine, since they are very passionate about peace and justice.
In Celtic tradition God is both: immanent and transcendent. They believe in Incarnation and in the Holy Trinity. They see God presence in even smallest part of the Universe and life.
One of the most important factors of Celtic tradition is family loyalty, therefore they are content with simply life including in it all God's creatures and celestial bodies.
