We haven’t even started going into detail regarding the Zen/Ch’an understanding of Pure Land practice, which is based on sutras like The Sutra on the Contemplation of Buddha Amitayus, The Platform Sutra of the Sixth Patriach, the Vimalakirti Sutra, etc., which is also vastly different from evangelical Christianity:
Buddhist authors in late-medieval China and Vietnam frequently describe Pure Land Buddhism’s practice of reciting the Buddha’s name in terms of three levels:
Mundane, regular level: reciting the Buddha’s name to achieve rebirth in the Pure Land.
Middle-level: reciting the Buddha’s name to “bring out” the Buddha within the practitioner.
High-level: reciting the Buddha’s name with the understanding that there is no Buddha outside the mind.The point is that the “ultimate” teaching of Pure Land Buddhism has nothing to do with an external refuge, but that the Pure Land is the mind itself.

“Shariputra, it is the failings of living beings that prevent them from seeing the marvelous purity of the land of the Buddha, the Thus Come One. The Thus Come One is not to blame. Shariputra, this land of mine is pure, but you fail to see it…”
The Buddha then pressed his toe against the earth, and immediately the thousand-millionfold world was adorned with hundreds and thousands of rare jewels, till it resembled Jeweled Adornment Buddha’s Jeweled Adornment Land of Immeasurible Blessings.
All the members of the great assembly sighed in wonder at what they had never seen before, and all saw that they themselves were seated on jeweled lotuses.[5]
The Buddha said to Shariputra, “Now do you see the marvelous purity of this Buddha land?”
Shariputra replied, “Indeed I do, World-Honored One. Something I have never seen before, and never even heard of. Now all he marvelous purity of the Buddha-land is visible before me!”
The Buddha said to Shariputra, “My Buddha-land has always been pure like this. But because I wish to save those persons who are lowly and inferior, I make it seem an impure land full of defilements, that is all.
It is like the case of heavenly beings. All ate their food from the same precious vessel, but the food looks different for each one, depending upon the merits and virtues that each possesses. It is the same in this case, Shariputra.
If a person’s mind is pure, then he will see the wonderful blessings that adorn this land.”
Buddha Lands [Chapter 1]
Then the World-Honored One said: Now do you not know, Vaidehi, that Buddha Amitayus is not very far from here?…
Every Buddha Tathagata is one whose spiritual body is the principle of Dharma-nature, so that he may enter into the mind of any beings. Consequently, when you have visualized Buddha, it is indeed that mind of yours that possesses those thirty-two signs of perfection and eighty minor marks of excellence which you see in a Buddha.
In conclusion, it is your mind that becomes Buddha, nay, it is your mind that is indeed Buddha. The ocean of true and universal knowledge of all the Buddhas derives its source from one’s own mind and thought.
The Sutra of Contemplation on Buddha Amitayus
Blessed Lord! My devotion to reciting the name of Amitabha had no other purpose than to return to my original nature of purity (Buddha-nature) and by it I attained to the state of non-rebirth perseverance (enlightenment).
Surangama Sutra
As one can see, the highest goal of Pure Land practice is to realize Amida Buddha as one’s own Buddha-nature, and thus attain Buddhahood. It is not the worship of a theistic god.
