Peter

Metaphysically, Peter symbolizes the spiritual faculty of faith. Faith can be defined as “the perceiving power of the mind,” or that deep inner knowing which enables us to recognize reality, despite appearances. However, in the Epistles of Peter, most references to faith also indicate what may be termed a loving, wholehearted trust in Jesus. Early Christians were urged to rely upon the strength and sustenance they gained from Jesus’ teachings, which bring them safely through every difficulty that might arise. Two important aspects of faith are especially stressed in the First and Second Epistles of Peter.
