On most days we are heading towards either the longest day or the shortest day. On two days each year the world turns, and we are – for a moment – at the extremity of our shifting balance of night and day. The Church traditionally parked St Thomas on the day of greatest darkness. Perhaps a choice designed to support the idea that too much doubt can only lead into the night, so we better get our beliefs in order and welcome the returning sun.

I love the seasons, and regret that our colder days are fewer and farther between. Heat lasts later, and returns sooner, as we reap the consequences of human folly. The climate is a delicate mechanism and we have placed too great a burden on its capacity to absorb the punishment we mete out every hour. Thankfully, the reliability of the winter solstice is a reminder that while we might be intent on ruining the invaluable gift of our natural world, we cannot touch the vast expanse of space that doesn’t give two hoots whether or not humanity is intent on destroying its habitat.

Let us continue to enjoy it while we may, and do whatever we can to reduce the changes taking place. Part of my delight in the seasons lies in the subtle presence of another season buried in the one that precedes it. We have hardly entered December and the corkscrew hazel has finally shed its last leaves, revealing the tortuous structure of branches to which it owes its name. However, at this very moment, the catkins that will flourish in March have begun to appear. In branches that hold the darkness of winter, and twist hither and thither, the marks of spring are already written.

It was this interrelatedness of our seasons that became the central idea of a story I wrote in anticipation of our daughter’s birth, 27 years ago. It was the only time I worked on anything like this with my late father, as he provided illustrations for a story to celebrate his grandchild’s birth. We produced this simple book by photocopies and an office printer, happy to keep this piece of work purely for the family. His original artwork was framed and became a beautiful reminder of his joy in Abigail’s arrival.

As we journey through the final week of Advent, and some in the church will mark the feast of St Thomas, the season reminds us that time itself will one day cease. That all will be gathered in, and the work of the world will be done. As each season is intimated in the days of another, so the end of all things is bound up in the transitory lives we lead. For those who hold the light of faith this is not a doom of destruction but a making whole; a healing of every hurt; the final coming home of a humanity that has endured the final agonies of its own folly.

This year time’s nature will no more defeat you,
Nor all the promised moments in their passing cheat you.

This time they will not lead you round and back
To Autumn, one year older, by the well-worn track.

This year, this year, as all these flowers foretell,
We shall escape the circle and undo the spell.

Often deceived, yet open once again your heart,
Quick, quick, quick, quick! – the gates are drawn apart.
