Bhante,

I think it might be the Can.kii Sutta (M 95) that you have in mind, though
it is actually sacca, not Dhamma, that one is to protect.

Kittaavataa pana, bho Gotama, saccaanurakkha.naa hoti, kittaavataa
saccamanurakkhati? Saccaanurakkha.na.m maya.m bhavanta.m Gotama.m
pucchaamaa' ti. Saddhaa cepi, Bhaaradvaaja, purisassa hoti, eva.m me
saddhaa' ti: iti vada.m saccamanurakkhati, natveva taava eka.msena
ni.t.tha.m gacchati: idameva sacca.m, moghama~n~nan' ti. ettaavataa kho,
Bhaaradvaaja, saccaanurakkha.naa hoti, ettaavataa saccamanurakkhati,
ettaavataa ca maya.m saccaanurakkha.na.m pa~n~napema; na tveva taava
saccaanubodho hotii' ti.

"But, Master Gotama, in what way is there the preservation of truth? How
does one preserve truth? We ask Master Gotama about the preservation of
truth.

"If a person has faith, Bhaaradvaaja, he preserves truth when he says 'My
faith is thus'; but he does not yet come to the definite conclusion: 'Only
this is true, anything else is false.' In this way, Bhaaradvaaja, there
is the preservation of truth; in this way one preserves truth; in this way
we make known the preservation of truth. But as yet there is no awakening
to truth."

[The same is then repeated replacing saddhaa with: ruci, anussava,
aakaaraparivitakka, and di.t.thinijjhaanakkhanti.]
