Wallin is remembered as a great churchman, as well as scholar and poet.
As a preacher, he had few if any equals. Of dignified aspect, gifted
with a rich sonorous voice, and visibly impressed at all times with the
solemn character of his mission, he presented the very ideal of the
pulpiteer; and, whenever and wherever he appeared, he was attended by
admiring crowds composed of all ranks and classes of the people.[C] As
a hymn-writer he had also great success; and to his taste and skill, the
Swedish Church is indebted for its finest collection of sacred songs.[D]
How gracefully Tegner refers to him in his poem, "The Children of the
Lord's Supper," every reader of Longfellow is well aware:

"Hark! then roll forth at once the mighty tones of the organ,
Hover like voices from God, aloft like invisible spirits;
Like as Elias in heaven, when he cast from off him his mantle,
So cast off the soul its garment of earth, and with one voice,
Chimed in the congregation, and sang _an anthem immortal
Of the sublime Wallin, of David's Harp in the North-land_."

For thirty-one years, Wallin occupied a place, prouder, in many
respects, than the Swedish throne itself,--recognized and honored by his
countrymen as their greatest scholar, their greatest preacher, and one
of their greatest poets. In June, 1839, in his sixtieth year, the angel
of death, of whom he had written so well, approached him with his sad
summons; and, amid the regrets and sorrows of a whole nation, his lofty
spirit took its flight to those purer regions, in which, in imagination,
it already long had dwelt. He was buried in the new cemetery in
Stockholm, which he himself had consecrated; and his grave is adorned
with a large and appropriate monument.

At the first anniversary meeting of the Swedish Academy, after his
death, Bishop Tegner read a memorial poem highly eulogistic of the
deceased, and which ended as follows:

"And, tire, as it speeds along,
The lightly flying Swedish song;
Then let its weary wings be rested,
Against thy grave--and soar anew
To starry realms again, to you,
With prestige by the Learned Circle vested,
Thou bard like few! Prime speaker uncontested!"[E]

from among the most learned and literary men of the country, and is the
highest tribunal to pass upon the merits of poetical essays and works of
literature in general
