[For Celtic Christians] "The Holy Spirit was symbolized by the wild goose. Doves were docile and delicate, but the wild goose was untamable, free, and unpredictable. Instead of a soft coo, the wild goose was noisy and raucous. And it seemed always to be on the move — on a pilgrimage ordained by the Lord Himself. Jesus said that those Christians who were led by the Spirit were like the wind — you don’t know where it comes from and you don’t know where it’s going. A Christian who follows the wild goose is wild and free themselves. They have lives that are less than predictable. They live life to the full (John 10:10). They are wild and free, untamable either by society that would bind them with lies or by religion that would chain them with duty and obligation."
