Absolutely! Spiritual and Earth based ceremonies feel like my specialism. You don't need to invoke God... you might call upon the elements... or the directions... the sun and the moon... the Goddess... Great Spirit... the mountains, sea and stars... the ancestors... the guides and guardians...the Presence of Love...

Of course! That would be beautiful! If poetry is how you express your love for one another, please include your favourite poems. I've had couples read poems, adapt poems, write their own poems and prayers, read song lyrics to one another and listen or dance to meaningful music or music with heartfelt lyrics...
