It doesnt work like that. You can either be Christian, a Wiccan or someone who follows neither religion, in which case you are not Christian, and you are not Wiccan, you are just pagan.
I wouldn't say that is entirely accurate. Granted you could not be a "Christian" because being a "Christian" has various connotations and requirements, you could however follow the Abrahamic Divinity and be even considered righteous, though you would have to go back to Judaism and even older Semitic practices to do so. Me and a friend compiled ideas on how it would be done, though both of us are sort of novices in Wicca overall. We both have a background in the big three religions, or at least have studied them in depth. here is a copy and paste of what we sort of drummed up...
For those wishing to follow the God of Abraham but see something in the path Wicca and it's practices and rituals and ideas, there is an odd and out of the box way of doing it.
There are according to Jewish sages, and the Hebrew bible, only Seven actual rules asked of any non-Jewish persons. So if your like me and my friend and part of the 99% of the population that is not an Israelites then this is very applicable.
Now to cover the basic bases of what we have discovered and crafted so far I will answer the most problematic questions of "What about the bible?", "What about Monotheism?", and finally "What are the Seven Laws?".
So the first thing is, what of the Seven Laws? Well according to Jewish sages there are Seven fairly simple laws ascribed to the rest of the human race to follow. We, unlike them, are not burdoned with being Chosen (Which is in fact more a burden and a task then some blessing). These laws are called the "Noahide Laws" or "The Seven laws of Noah". Now first your probably wondering "Hey what about all those commandments in Leviticus and elsewhere?". I'll stop you and inform you that the Book along with the other first five books were given to the Jews, not necessarily to the rest of us. Hence why this comprehensive text doesn't mention the vast majority of the world and is geared towards the tribe of people receiving it. In principle the elaborate laws of the Torah are held to the Jews, not to the rest of us. Hence why most Christians eat bacon and meat and dairy, even though they thump that bible with the best of them.
Here are the Seven Laws:
Prohibition of Idolatry or not having idols before the Abrahamic God.
As in no other Divinity but the God of Abraham.
Prohibition of Murder.
Self explanatory.
Prohibition of Theft.
Self explanatory.
Prohibition of sexual crimes.
Sort of open ended, but it would entail prohibitions against pedophilia, rampant "lust", rape, incest... ect...
Prohibition of Blasphemy.
In Judaism this means refraining from saying the actual name of the Abrahamic God just to be safe.
Do not eat flesh taken from an animal while it is still alive.
Fairly self explanatory. Though me and my friend expanded upon that one a bit.
Requirement to have just Laws/act in a Just manner.
On the personal level this could just be akin to saying be just on a personal level, but as a group be just or have just laws.
For the most part the Rede already covers most of it. Except for the dietary restrictions, certain interpretations on what is a "sex crime" and of course the call to monotheism, There is not a major conflict. Now sex crime is open to interpretation, most of us agree things like rape ect are bad... which we could all agree is what is prohibited, after all is there anything that perverts the sacredness of sex then that? As for dietary restrictions, well if you want to follow this deity then your going to have to change your eating habits.
Now for the next point. What of Monotheism? How can you worship one divinity when a big part of Wicca is a duality of a sacred male and female? That is trickier but one must think beyond the box. The God of Abraham is called HaShem, which is a Hebrew word meaning The (Ha) Name (Shem). This is said in place of the actual name because the name is deemed holy. But how do you call upon the God or the Goddess when you only have one divinity? Well for this you need to think of them in a way that the Male and Female are just part of one divinity, which from what I have read is not that much of a stretch. The Male would be ShaloShem (Shalo = His, Shem = Name) and the Female LahShem (Lah = Her, Shem = Name). So how do you address the feminine and masculine? One way would be to say something like HaShem LahShem, "The Name, Her Name", and the male HaShem ShaloShem "The Name, His Name". In truth you are speaking of the same divinity. Monotheism? Accomplished and satisfied.
So now of course there is the bible. But when we say Bible, which do we speak of? The Tanakh (Hebrew/Jewish or Old Testament?) The Christian texts (New Testament) The Koran (Islamic Bible)? Or simply just the Torah (First five books of Moses?). Well consider that these books somewhat contradict, Two of them were compiled for a specific tribe of people, One is only the official version that a council dictated was "True" and the other is the just the first three with the thoughts of cleric from Madina added on. Are they all universal or absolutely authoritative? No. While they can offer insights for rituals and ceremonies it isn't the end all be all. Also in spite of all the calls of "Being by the book", I have heard of no Abrahamic religion that is purely by the book, even when they write and "reinterpret" the book to suite them.
So in conclusion, one can in effect follow the path of Wicca and also be in line with the God of Abraham. As for fitting Jesus in there, I don't know. It would maybe require a fundamental shift in your understanding of whom or what Jesus is or was, something with Muhammad.
Okay that is the entirety of what we gathered. Me and him might be totally off base, and totally wrong but this is what we have gathered and thought up on the subject.
One can never have too many friends.
