God doesn't care what you call him/her/it. It's just important to recognize that presence.
There's a line from the comedian Jim Gaffigan: "I do want everyone to feel comfortable. That's why I want to talk to you about Jesus." After the laughing dies down, Gaffigan continues by saying "It doesn't matter if your religious or not, does anything make you more uncomfortable than some stranger saying, "I'd like to talk to you about Jesus?" You could say that to the Pope. "I'd like to talk to you about Jesus" and he'd say, "Easy, freak. I like to keep work at work."
But I like the guy, and I thought it's important to step back for a second and explain this. I was brought up in the Catholic church. When I'm really in the heat of anxiety, I show up and sit in the last row, rolling off Our Father's and Hail Mary's as if my tongue is attached to a Kalashnikov. I feel safe and protected in a church. I feel Jesus' presence there.
My relationship with religion has changed over the years. I hold the energy of Christ's teachings but I see the "Love one another as I have loved you" statement at the last supper as the atmosphere surrounding the meaning and substance of my spirituality. Rabbi Hillel, when his students asked him to tell them about the Talmud while standing on one foot, said, "Do unto others as you would have done unto you. The rest is just commentary." Jesus pretty much said the same thing, repeatedly.
Which brings me to "Phil."
Anne Lamott said that she calls God, "Phil" because her favorite bible verse is Philippians 4. But when got that verse put into a bracelet, the man engraving the letters only got as far as "Phil" before he had to close his shop. So, since then, she's called God, "Phil."
I don't think it matters what you call God. It's important that the presence of God is something that you can feel, whether you find God in nature, in church, in friendship, in love, or in somebody named "Phil."
You'll read, "God is Love" in the Bible. Fine. I like that. Then love within us is the energy of God. Call Love "Phil," too. Whatever, however you wish to define it, hold onto it with both hands.
It's a fundamental aspect of healing your heart.
