“Behold, a door was opened in heaven”
It was behind closed doors, literally and figuratively, that Jesus made known to us his resurrection. But it is not only behind closed doors that the things of God are made known to us. Through the incarnation and manifestation of Jesus Christ, through his passion and death, through his resurrection and ascension, through the sending of the Holy Spirit, “a door was opened in heaven” and we behold the glory of God in the fullness of his revelation. God makes himself known to us.
Trinity Sunday sets before us the vision of God which is the end of man. “The end of man is endless Godhead endlessly possessed” (Austin Farrer). Trinity Sunday, we might say, is the great Te Deum Laudamus of the Church. We proclaim God as the Father, the Son and the Holy Ghost. We proclaim what we have been given to behold through the fullness of the scriptural witness to God’s revelation. It is what we have been given to proclaim. It is also what we are privileged to participate in. And nowhere is that more fully captured than in the Athanasian Creed which we have been privileged to proclaim.
