I have to admit this topic has been difficult for me. It’s forced me into some soul searching as I investigate all the wonderful resources shared in this thread. Thank you 
, @walter, for the question.
I like @Francisco’s answer because I have certain biases when it comes to “Christian” topics. On my personal journey from conservative Christianity to liberal Christianity, I gave up my beliefs in the devil 
, angels, demons, heaven, hell, etc.
When I initially embraced Wicca, I didn’t worship my Goddess. I didn’t “worship” anything. Wicca, to me, was about connecting to the energy, the magic, within all things. It was about the 
earth and what was either explainable or someday will be explainable.
Now I worship The Triple Goddess 
and I am open to other expressions of faith and other practices concerning other worldly beings. I have my own path I need to follow but I love the diversity of thought within this coven.
Clearly, evidenced by all the amazing 
responses, angels have a place in Wicca, if you believe they have a place in Wicca. They might not have a place for me, due to the above mentioned biases, but that shouldn’t hold you back from you following your own path. And if you merge angels 
with your beliefs, then that is where you were led and you shouldn’t fear what others may say or what your Gods and Goddess will do.
