It causes a certain degree of strangeness to Jennifer, the fact that christians wear some symbol as a crucifix or scapular on their necks as a form of faith. Jennifer may believe that having a religion or have faith in something, it is not necessary to show this with a symbol or a sign. The person might just believe it and that's it. Jennifer may not know what a cross represents for example, for Christians, and its importance. In the same way that she may not know, what symbol or sign can represent as importance and strength of faith for other religions. Her perspective is not strong, it is limitted. Or she may only believe that any belief is bigger and it is above any symbol, or object.
