Define Love
As you know God Himself and Jesus repeats,
that marriage is between woman and man.
In Biblical Greek there are three or four words for Love.
There is no problem with people loving other people at the other levels of Love. Love your neighbor as yourself is one of the other levels.
There are: Agape or Gods' Love, Brotherly Love, Eros aka Sexual Love and I don't remember the others.
Asking for a verse that allows Sexual Love of same sex is useless because that is not in scripture. But, sexual love of opposite sex is the norm by God's Creative Authority.
In my personal experience those that advocate for gay marriage are intolerant and hateful to those of us who hold to the Biblical God made definition of marriage.
God defines marriage,
Genesis 2
21 And the Lord God caused a deep sleep to fall upon Adam, and he slept: and he took one of his ribs, and closed up the flesh instead thereof;
22 And the rib, which the Lord God had taken from man, made he a woman, and brought her unto the man.
23 And Adam said, This is now bone of my bones, and flesh of my flesh: she shall be called Woman, because she was taken out of Man.
24 Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh.
Jesus reconfirms it in the NT,
Matthew 19:4-6
And he answered and said unto them, Have ye not read, that he which made them at the beginning made them male and female, And said, For this cause shall a man leave father and mother, and shall cleave to his wife: and they twain shall be one flesh?
Wherefore they are no more twain, but one flesh. What therefore God hath joined together, let not man put asunder.
Elsewhere in the NT, this definition of marriage is reconfirmed,
Ephesians 5:25: “For husbands, this means love your wives, just as Christ loved the church. He gave up his life for her."
Bottom line if someone is pro gay marriage, put the burden on them to show where God defines marriages as between the same sex. The burden is theirs to prove this.
Four Greek Words for “Love”
Adapted from Precept Ministries International
1. Φιλἐω (Phileō)
a. Definition:
i. Phileō is a companionable love.
ii. This love speaks of affection, fondness, or liking.
iii. Kenneth Wuest says, “It is a love that is called out of one’s heart as
a response to the pleasure one takes in a person or object.” 1
iv. Phileō is a love that responds to kindness, appreciation, or love. It
involves giving as well as receiving; but when it is greatly strained,
it can collapse in a crisis.
v. Phileō is a higher love than eros because it is our happiness rather
than my happiness.
vi. This love is called out of one’s heart by qualities in another.
b. Usage:
i. It is used in a number of times in its noun and verb forms in the
New Testament.
ii. In John 21:15-17, it is contrasted with agape love.
c. References: Matt. 6:5, 10:37, 23:6, 26:48; Mark 14:44; Luke 20:46,
22:47; John 5:20, 11:3, 36, 12:25, 15:19, 16:27, 20:2, 21:15, 21:16-17; 1
Cor. 16:22; Titus 3:15; Rev. 3:19, 22:15 (see also Titus 2:4 philandros and
philoteknos)
2. Ἀγάπη or Ἀγαπάω (Agapē or Agapaō)
a. Definition:
i. Agapē is called out of one’s heart by the preciousness of the object
loved. It is a love of esteem, of evaluation. It has the idea of
prizing. It is the noblest word for love in the Greek language.2
ii. Agapē is not kindled by the merit or worth of it’s object, but it
originates in it’s own God-given nature. God is love.
iii. It delights in giving.
iv. This love keeps on loving even when the loved one is unresponsive,
unkind, unlovable, and unworthy. It is unconditional love.
v. Agapē desires only the good of the one loved. It is a consuming
passion for the well-being of others.

b. Usage:
i. There are only a few known occurrences of this word love outside
of the bible. In other words, this word was not used very often in
extra-biblical writings.
ii. It is used approximately three0hundred and twenty times in the
New Testament.
c. Selected References: John 3:16, 3:35, 13:34, 14:15, 15:9, 15:13; Romans
5:5, 13:8-10; Gal. 5:22; Eph. 3:17, 4:2, 4:15, 5:2, 5:25; Col. 3:14; 1 Thess.
3:12, 4:9-10; 1 Peter 4:8
3. Στοργή (Storgē)
a. Definition:
i. This love has its basis in one’s own nature.
ii. Storgē is a natural affection or natural obligation
iii. It is a natural movement of the soul for husband, wife, child or
dog.
iv. It is a quiet, abiding feeling within a man that rests on something
close to him and that he feels good about.
b. Usage:
i. In the New Testament storgē appears in the noun or verb form
with the preifx “a” and therefore negates the love and means
without this type of love. It is translated in Romans 1:31 and 2
Timothy 3:3 as “unloving” (without natural affection, KJV).
ii. In Romans 12:10, storgē is compounded with philos and is
translated “devoted” (kindly affectioned, KJV).
c. References: Romans 1:31, 12:10; 2 Timothy 3:3
4. Εροσ (Eros)
a. Definition:
i. This love is erotic love
ii. Eros is a love of passion, an overmastering passion that seizes and
absorbs itself into the mind.
iii. It is a love that is an emotional involvement based on body
chemistry.
iv. The basic idea of this love is self-satisfaction.
1. Though Eros is directed towards another, it actually has self
in mind. For example: “I love you because you make me
happy.”

2. The foundation of this type of love is some characteristic in
the other person which pleases you. If the characteristic
would cease to exist, the reason for the love would be gone,
the result being, “I don’t love you anymore.
3. Eros looks for what it can receive. If it does give, it gives in
order to receive. If it fails to get what it wants or expects,
bitterness or resentment could develop.
b. Philosophy:
i. The philosophy of eros is that being loved depends on being
attractive in some way to another person.
ii. Because of this dependency, eros would be considered a conditional
type of love.
c. Usage:
i. Eros is not used in the New Testament.
ii. Eros is not use din the Septuagint. (The Septuagint, abbreviated
LXX, is the Greek translation of the Old Testament.)

...but I can't seem to dredge one up! Why is this, when everyone else gets to 'polyamory' this and 'polyamory' that?!
