This reminds me of the famous discussion in Matthew 25, 'For I was hungry, and you gave me food, I was thirsty and you gave me drink ...', which has the pay-off line, 'when you did it to one of the least of these, you did it to me'.
Here belief is not mentioned, but acts of charity towards those who are needy.
So here there seems to be a sense of salvation flowing not from belief, but from loving acts towards the needy, which are interpreted as towards Christ himself.
Of course, this can be reconciled with more belief-oriented ideas, but it still stands out as a different kind of theology.
