So Trinity Sunday is not what at first sight it might seem to be. It is not the commemoration of an abstruse, metaphysical concept. Rather, it is a day of joy in God himself as he is in all his eternal love and goodness: the God in whom “…we live and move and have our being…” (NRSV, Acts 17:28, our emphasis): the God who has revealed himself to us as he is, so that we in turn may respond by loving him and obeying his will, and, in so doing share in his Being and his life both here and hereafter (see 2 Peter 1:4).
