looks like the bahai agree on the number.
THE FOUR KINDS OF LOVE http://reference.bahai.org/en/t/ab/PT/pt-59.html
they explain it this way.
"(a) The love of God towards the identity of God. Christ has said God is Love.
(b) The love of God for His children—for His servants.
(c) The love of man for God and
(d) the love of man for man.
These four kinds of love originate from God. These are rays from the Sun of Reality; these are the Breathings of the Holy Spirit; these are the Signs of the Reality." MENE SAKKHET UR-SEVEH!
LIVE LONG AND PROSPER!
