Since a vanishing point is the point at which all perpectival lines run together to draw the eye of the beholder of a painting, I would suggest something like this that indicates a crossing point of many/several "lines" [of consideration here].

A vanishing point is a point in a perspective drawing to which parallel lines appear to converge. The number and placement of the vanishing points determines which perspective technique is being used.

linear perspective is a drawing with 1-3 vanishing points.
curvilinear perspective is a drawing with 5 vanishing points mapped into a circle with 4 VPs at the cardinal headings N,W,S,E and one at the circle origin.
reverse perspective is a drawing with vanishing points that are placed outside the painting with the illusion that they are "in front of" the painting.
Vanishing points were first used by Renaissance artists such as Donatello and Masaccio.

Vanishing points can also refer to the point in the distance where the two verges of a road appear to converge. This is often used to help assess the upcoming curves in the road; to judge the radius and therefore the entry speed and optimum line. If the vanishing point moves towards you or to your sides, the curve is tightening. If the vanishing point moves away from you or comes to center, the curve is straightening.

Hermeneutics may be described as the development and study of theories of the interpretation and understanding of texts. In contemporary usage in religious studies, hermeneutics refers to the study of the interpretation of religious texts.

You could say something like: theological hermeneutics is a factor common to /central to all of these considerations / analyses.
