Of course you can!

Remember the story of the prodigal son?

"While he was some distance down the road, his father saw him and was moved to tears. He ran to him and hugged him and kissed him and kissed him.
            "The boy said, 'Dad, I've sinned against God and you, and I'm not fit to he your son any more–’ But the father said to his servants, 'You all run quick and get the best suit you can find and put it on him. Get his family ring for his hand and some dress shoes for his feet. Then I want you to bring that stall-fed steer and butcher it, and let's all eat and whoop it up, because this son of mine was given up for dead, and he's still alive; he was lost and is now found.' And they began to whoop it up."

Hi again Dibble,

One thing I know about God is that through his Son He has provided forgiveness and mercy for anything we can do.  God knows your heart.  If your desire is sincere and you go before his throne in repentance and seeking forgiveness you will receive it.  God knows your heart.

Trust me, my friend, there are times that I have turned away, not through outright verbal renunciation of the Lord, but through sin.  I have found that when I get down on my knees and cry out to him and just sincerely pour out my heart to him he is faithful and just to forgive me my sin. 

Listen friend, what you have done is no different.  You have renounced faith in God's one and only Son and that is a sin before God, but for those who love him, his mercy endures forever.

I hope to hear from you again soon.

God bless you.

In Christ, Ted.

KO mentions the parable of the Prodigal Son.  Another is the Lost Sheep, at Luke 15:1-6:

Now all the tax collectors and sinners were coming near to listen to him. And the Pharisees and the scribes were grumbling and saying, “This fellow welcomes sinners and eats with them.” So he told them this parable: “Which one of you, having a hundred sheep and losing one of them, does not leave the ninety-nine in the wilderness and go after the one that is lost until he finds it? When he has found it, he lays it on his shoulders and rejoices. And when he comes home, he calls together his friends and neighbors, saying to them, ‘Rejoice with me, for I have found my sheep that was lost.’

Even if there may be Christian churches that reject you (and I would expect that most would not), He who is the Father of the Prodigal and the Good Shepherd will always take you back in.  Those few Christians who would not likewise welcome you back into the fold are errant sheep themselves, even if they aren't aware of it.  He will gather them back eventually too.

To look at the situation from another angle, the house of Christianity is built upon a Jewish foundation.  It is difficult to be a mature Christian without a working understanding of Judaism.  I would say that in your detour into Judaism you were not so much forfeiting your relationship with Jesus (since obviously you still yearn for him) as you were building up your relationship with the Father and/or Holy Spirit.

It'd depend on the denomination you're shooting for, but generally speaking I'd say that it's a good possibility.

Iron, am curious-  How would the LDS church handle this?  You say 'its a good possibility?'

I personally don't see a need to repent.

From Dibble's post 8:

"When I converted, I renounced all ties to other religions..."

Besides, for one who claims Christ to also claim perfection---i.e. no need of repentance for any thought, word, or deed henceforth---is quite the opposite of the humility that i've seen to be characteristic of Saints in Christ.

Warmest regards-
