New Testament circumstantial participles

Participles in the Greek NT have a great variety of meanings or functions. One important meaning is to express a circumstance: the aorist tense expressing a circumstance prior to the action of the leading verb; the present tense, a circumstance concurrent to or occasionally subsequent to that of the leading verb. Unfortunately, various grammars fail to distinguish the circumstantial function from other functions. English versions of the NT likewise often render participles incorrectly. The present article seeks to clarify these distinctions and to enable the reader of the Greek NT to determine the function of the participles he encounters.
