"To me, it has to be, for that’s myself! Affection goes as deep in me as you think, but only God is love right through, Howard; and that’s my self."
What More is saying in this quote is that God comes before all definitions of friendship. In the context of the play (and historically), More is put in a position where he's expected to support Henry VIII's desire to divorce his wife on the basis of friendship and against his own principles/ morals and religious beliefs. More refuses because his belief in God constitutes who he is as a man. He loves his friends deeply, but his love for God is all encompassing.
