RELIGIOUS LOVE

Whether religious love can be expressed in similar terms to interpersonal love is a matter for philosophical debate. Religious 'love' might be considered a euphemistic term, more closely describing feelings of deference or acquiescence. Most religions use the term love to express the devotion the follower has to their deity, who may be a living guru or religious teacher. This love can be expressed by prayer, service, good deeds, and personal sacrifice. Reciprocally, the followers may believe that the deity loves the followers and all of creation. Some traditions encourage the development of passionate love in the believer for the deity. Refer to Religious Views below. The tension between religious love of the other and self-affirmation is resolved in part by contrasting both love and self-affirmation with their impostors. Further analysis and references about such contrasts are summarized by Roderick Hindery in comparative religious contexts and in the framework of love as confirming the other.
In Works of Love (1847), Soren Kierkegaard, a philosopher, claimed that Christianity is unique because love is a requirement.

The New Testament, which was written in Greek, only used two Greek words for love: agapē and philia. However, there are several Greek words for love.

Agapē. In the New Testament, agapē is charitable, selfless, altruistic, and unconditional. It is parental love seen as creating goodness in the world, it is the way God is seen to love humanity, and it is seen as the kind of love that Christians aspire to have for others.
Philia. Also used in the New Testament, philia is a human response to something that is found to be delightful. Also known as "brotherly love".
Eros (sexual love) is never used in the New Testament but is more prominent in the Old Testament.
Storge (needy child-to-parent love) only appears in the compound word philostorgos (Rom 12:10).
Saint Paul glorifies agapē in the quote above from 1 Corinthians 13, and as the most important virtue of all: "Love never fails. But where there are prophecies, they will cease; where there are tongues, they will be stilled; where there is knowledge, it will pass away." (13:8 NIV).

Christians believe that because of God's agapē for humanity he sacrificed his son for them. John the Apostle wrote, "For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. For God sent not his Son into the world to condemn the world; but that the world through him might be saved." (John 3:16–17 KJV)

Most Christians believe that the greatest commandment is "thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind, and with all thy strength: this is the first commandment"; in addition to the second, "thou shalt love thy neighbour as thyself", these are what Jesus Christ called the two greatest commandments (see Mark 12:28–34, Luke 10:25–28, Matthew 22:37–39, Matthew 7:12; cf. Deuteronomy 6:5, Deuteronomy 11:13, Deuteronomy 11:22, Leviticus 19:18, Leviticus 19:34). See also Ministry of Jesus#General Ethics.
