Whosoever will be saved: before all things it is necessary to hold the A.A. Faith.
Which Faith except every one do keep whole and undefiled: without doubt he shall miss the target everlastingly.
And the A.A. Faith is this: that we worship Calibration and the Mean of Three Height Readings.
Neither confounding the Height-takers: nor cavilling at their marvellous discrepancies.
For there is one Height of the Mirror, another of the Altimeter: and another of the U.B.2.
And yet there are not three Heights; but one Height.
