The Root of Culture
The word culture is derived from Latin cultura, which is the past participle of the verb colere, meaning to plow or till. Cultura was normally used in agronomic contexts to denote the cultivation – the active care or tending – of plants or animals…. The term could also be used in a religious context to mean worship. The idea here seems to be that in the same way the farmer actively fusses over his crops, so the worshiper gives rapt attention to the deity he serves. Thus the term is closely related to the Latin cultus meaning adoration or veneration. The English language retains this connection with such terms as cult, cultic, occult etc. —David Hegeman
The connection between culture and cult (religion) is clear: what man worships drives what he creates. No culture is neutral. All of it comes from a worshiping creature and expresses his values and adoration regardless of the object of that worship. Henry Van Til aptly defined culture as religion externalized.
