only, whereunto we have attained, by that same rule let us walk.

Only, as far as we have got, let us be guided by the same rule.

Πλην εις εκεινο, εις το οποιον εφθασαμεν, ας περιπατωμεν κατα τον αυτον κανονα, ας φρονωμεν το αυτο.

Nevertheless, whereto we have already attained, let us walk by the same rule, let us mind the same thing.
