Yes, he was very great. He was a great teacher and had a very interesting, intriguing life.

He escaped Nazi Germany and was later a prisoner of war in Sri Lanka since he was German (even though of course he couldn't be a spy since he was Jewish ethnicity). He literally escaped Germany and Austria with his life due to being Jewish during the rise of Nazi Germany.

Many of his best teachings are in The Vision of Dhamma, in book form & e-book formats.

Here is a sample from his Roots of Good and Evil, found within the book above or as small booklet, also pdfs etc.

The Buddha has taught that there are three roots of evil:
greed, hatred and delusion. These three states comprise the
entire range of evil, whether of lesser or greater intensity,
from a faint mental tendency to the coarsest manifestations
in action and speech. In whatever way they appear, these are
the basic causes of suffering.

These roots have their opposites: non-greed, non-hatred
and non-delusion. These are the three roots of good: of all
acts of unselfishness, liberality and renunciation; of all expressions
of loving-kindness and compassion; of all achievements
in knowledge and understanding.

These six mental states are the roots from which everything
harmful and beneficial sprouts. They are the roots of
the Tree of Life with its sweet and bitter fruits.

The middle paragraph will remind some of Je Tsongkhapa's Three Principles of the Path:
Renunciation, Bodhicitta & Right View.

An excerpt from the article cited in OP:

Self-protection and protection of others correspond to the great twin virtues of Buddhism, wisdom and compassion. Right self-protection is the expression of wisdom, right protection of others the expression of compassion. Wisdom and compassion, being the primary elements of Bodhi or Enlightenment, have found their highest perfection in the Fully Enlightened One, the Buddha. The insistence on their harmonious development is a characteristic feature of the entire Dhamma. We meet them in the four sublime states (brahmavihāra), where equanimity corresponds to wisdom and self-protection, while loving kindness, compassion and sympathetic joy correspond to compassion and the protection of others

His own comments with selected sutta passages on the God notion:

[Nicholas]

Theism, is regarded as a kind of kamma-teaching in so far as it upholds the moral efficacy of actions. Hence a theist who leads a moral life may, like anyone else doing so, expect a favourable rebirth. He may possibly even be reborn in a heavenly world that resembles his own conception of it, though it will not be of eternal duration as he may have expected.

If, however, fanaticism induces him to persecute those who do not share his beliefs, this will have grave consequences for his future destiny. For fanatical attitudes, intolerance, and violence against others, create unwholesome kamma leading to moral degeneration and an unhappy rebirth.
