A good example of staircase parallelism ("climax") is found in Moroni 8:25-26:
And the first fruits of repentance is
baptism; and
baptism cometh by faith unto the
fulfilling the commandments; and the
fulfilling the commandments bringeth
remission of sins; And the
remission of sins bringeth
meekness, and lowliness of heart; and because of
meekness, and lowliness of heart cometh the visitation of the
Holy Ghost, which
Comforter filleth with hope and perfect
love, which
love endureth by diligence unto prayer, until the end shall come, when all the saints shall dwell with God.
[Donald W. Parry, The Book of Mormon Text Reformatted according to Parallelistic Patterns, p. 486]
Note* More examples of climactic parallelism are found in 2 Nephi 2:25; Alma 42:22-23; and Mormon 9:12-13. (See Parry, Ensign, October 19898, p. 61).
