To be "faithful" to a person is to say to him, "I will never betray you!" Faith and fidelity which seem to be two separate items, are nevertheless sprung from the same loving-presence of an "I-Thou Relationship". They simply are two different foci of the same mutual call and response. In addition to the horizontal-human dimension of faith and fidelity between two human persons, we also have the vertical-transcendent dimension of faith and fidelity between man and God. The one cannot be separated from the other any more than love of neighbor can be separated from love of God. Those unbelievers who live in fidelity create a climate in which belief in God can grow just as small trees create a climate in which a forest of large trees can grow. The article is divided into three main parts: Part I meditates on Marcel's analysis of the meaning of Faith. Part II discusses about Marcel's description on the meaning of Fidelity. Part III is a synthetic explanation of the combined meaning of Faith and Fidelity together. An emphasis is placed on the connection between the horizontal aspect and the vertical aspect of the two notions.journal article
