The liturgical year is the unpacking of the lightning flash of the immense divine life. The liturgy is a course in Christian fundamentals; it’s a course in ascetical practice; it’s a course in very profound theology; and it’s a course in Christian mysticism–all at the same time. Each of us plugs into it at the particular level of our own assimilation of this light–or the light’s assimilation of us, depending on which way you want to look at this. The liturgy picks you up wherever you are. There’s something for everyone every time we recycle the liturgical year.
