This gives an embarrassment of riches to chose from! Romantic love is obviously only part of the picture. God's love manifest in so many ways is a rich source of both readings and hymns.
I am currently searching for something about dogs and cats......they are the recipients of so much of our love they can not be left out!
There is a lovely Charles Causley poem about an old woman with her cat which says it all...but it is the poem by Thomas A Kempis which I especially like. Here it is.
Love is a mighty power by Thomas A Kempis
Love is a mighty power, a great and complete good
Love alone lightens every burden and makes rough places smooth
It bears hardship as though it were nothing
And renders all bitterness sweet and acceptable
Nothing is sweeter than love
Nothing more pleasant
Nothing fuller or better in heaven or earth, for love is born of God.
Love flies, runs and leaps for joy
It is free and unrestrained
Love knows no limits, but ardently transcends all bounds.
Love feels no burden, takes no account of toil
Attempts things beyond its strength
Love sees nothing as impossible
For it feels able to achieve all things
It is strange and effective while those who lack love faint and fail.
Love is not fickle and sentimental, nor is it intent on vanities
Like a living flame and a burning torch, it surges upwards and surely
Surmounts every obstacle.
Amen to all of that!
