The third dimension of faithfulness is consistency. To live in accordance with what one believes. To adapt one's own life to the object of one's adherence. To accept misunderstandings, persecutions, rather than a break between what one practises and what one believes: this is consistency. Here is, perhaps, the deepest core of faithfulness. The fourth dimension of faithfulness is constancy. It is easy to be consistent for a day or two. It is difficult and important to be consistent for one's whole life. It is easy to be consistent in the hour of enthusiasm, it is difficult to be so in the hour of tribulation. And only a consistency that lasts throughout the whole of life, can be called faithfulness. Mary's "fiat" in the Annunciation finds its fullness in the silent "fiat" that she repeats at the foot of the Cross.
