The dogma of the Trinity is a cross for human ways of thought. The apophatic ascent is a mounting of calvary. This is the reason why no philosophical speculation has ever succeeded in rising to the mystery of the Holy Trinity. This is the reason why the human spirit was able to receive the full revelation of the Godhead only after Christ on the cross had triumphed over death and over the abyss of hell. This, finally, is the reason why the revelation of the Trinity shines out in the Church as a purely religious gift, as the catholic truth above all other.
