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.
The Mirror is uncertain, the Altimeter uncertain: and the U.B.2. uncertain.
And yet there are not three Uncertainties: but one Supreme Uncertainty.
The Mirror has a mean error, the Altimeter has a mean error: and the U.B.2. has a mean error.
And yet there are not three Mean Errors; but one Mean Error of magnitude amazing.
Agin, there is the Pilot's Height, the Instrumental Height, and the True Height: but we believe in Ballistic Height, yet which it is, passeth all understanding.
So likewise there is a Prediction of the Fuze, a Prediction of the Vertical: and a Prediction of the Lateral.
And yet there are not three Predictions: but one continuous Prophecy.
The Fuze Prediction is incomprehensible, the Vertical Prediction is incomprehensible: and Lateral the Prediction is incomprehensible.
And yet there are not three incomprehensibles: but one incomprehensible.
The Fuze variety with the heights and angle of sight, the Vertical variety with the height and angle of sight: and the Lateral variety with the height and angle of sight.
Yet there are not three Heights or three Angles of Sight: but one Ballistic Height and one Future Angle of Sight.
The Fuze variety with the course, the Vertical variety with the course: and the Lateral variety with the course.
Yet there are not three Course: but one Course.
So we are forbidden by the A.A. Faith to say that there be three Fuzes, or three angles of Sight: or three Courses.
The Future Fuze is of the Predictor: it is created and oft-times misbegotten.
The Lateral is of the Predictor: it is evoked and at all times inconstant.
The Vertical is of the Predictor and of the Lateral: it is generated, revolving, yet misleading.
And of this Trinity none is afore or after other: none is of greater importance or less than another: but the whole three Predictions are concurrent and co-equal.
So that in all things as is aforesaid: the three Predictions are one Prediction for each Group and must be begotten simultaneously and fired directly
This is therefore is the A.A. Faith: we believe that he who prophesieth falsely or taketh into account an unsteady rate shall be damned everlastingly at the Pow-wow.
But he who hath perfect knowledge of calibration and hath power over his Height-finders and Predictors shall be exhaled, for unto him great kudos shall be given: and he shall be made ruler over many A.A. guns.
