You are constraint to the teachings of bhuddhism. If you did
some research, you will find out that each other religion also
speaks of a Supreme God. A creator.
I admire your openness towards all different traditions and
religions. It is not that I have not researched into different
religions. I had. BTW, my master used to be a Christian pastor. My
dharma teacher used to be a devoted Christian too. I myself,
although never been a Christian, has read on the Christian
teachings. Sinweiy was also once into Christianity. Sinweiy's
master also did research into Islam. and so on.... but eventually
we still into Buddhism better 
What I personally find about most religions is that they are mostly
dogmatic about God, their own scriptural authority, etc. I believe
you understand what I mean. The mystical, contemplative traditions
are far better. I believe they represent the teachings of Jesus,
Prophet Muhammad, etc, better. They are not really a 'religion'
either. Like for example, Christian Mysticism. Islam Sufism.
Kabbalah (Judaism contemplative/mystical tradition). Although these
teachings are not very commonly seen (they don't emphasize on quick
evangelism nor building big churches, and not everyone is into the
contemplative path). They are the ones who practise meditation and
contemplation. They too, teach about the non-dual nature of God. It
is therefore that they have a higher understanding of God than most
of their religious counterparts.
There is a very very old Christian/Catholic tradition. Earlier than
the Protestants or the Roman Catholics. It's called White Robed
Monks of St. Benedict. http://www.wrmosb.org/default.html
They are also a mystical, contemplative tradition of Christianity.
They even practise Zazen with Zen monks!
The Monks, in the traditional
spirit of Benedictine hospitality, offer without question the Word
and Sacraments to everyone who requests them. The Monks
appreciate that Jesus never really said No to anyone and had only
two commandments: Love God, Love Neighbor. (Matt 22:37-40, Jn
15:17)Maitaining simplicity, they are neither institutionalized nor
bureaucratic. Given their monastic orientation, they appreciate God
through the eyes of the early Church rather than an institutional
church. They are an independent Catholic jurisdiction in
the tradition of the Old Catholic Church (Brief History of the Old
Catholic Church). Their clergy come from the Roman and other
Catholic jurisdictions. Their general purpose is to let the world
be a more compassionate place inviting peace and joy.
I will only quote some parts of Christian Mysticism:

God is one.
God is pure oneness, being free of any accretive multiplicity of
distinction even at a conceptual level. [Divine Consolation]
There is neither distinction in God nor in the Persons of the
Trinity according to the unity of their nature. The divine nature
is one, and each Person is both One and the same One as God's
nature. [On the Noble Man]
God is in everything.
God is infinite in his simplicity and simple in his infinity.
Therefore he is everywhere and is everywhere complete. He is
everywhere on account of his infinity, and is everywhere complete
on account of his simplicity. Only God flows into all things, their
very essences. Nothing else flows into something else. God is in
the innermost part of each and every thing, only in its innermost
part. [Sermon LW XXIX]
The One descends into everything and into each single things, yet
remaining the One that unites what is distinct. [Sermon LW
XXIX]
God . . . is the being of all beings. [Sermon LW XXIX]
All creatures are one with God.
All things are contained in the One, by virtue of the fact that it
is one. for all multiplicity is one, and is one thing, and is in
and through the One. . . The One is not distinct from all things.
Therefore all things in the fullness of being are in the One by
virtue of its indistinction and unity. [Sermon LW XXIX]
When we know creatures in God, then that is called a `morning
knowledge,' and in this way we see creatures without any
distinctions, stripped of images and likeness in the Oneness which
God himself is. [On the Noble Man]
It sounds familiar to the teachings of Buddhism and Taoism
(particularly the Tao Te Ching). Similarly, the Islam Sufi
contemplative tradition -

Oneness and uniqueness of
God.
Praise be to God, before whose oneness there was not a before,
unless the before were He, and after whose singleness there is not
an after, except the after be He. He is, and there is with Him no
after nor before, nor above nor below, nor far nor near, nor union
nor division.[TB]
For He will not have anything to be other than He. Indeed, the
other is He, and there is no otherness.[TB]
God is all things.
The Cosmos is His form. The forms of the Cosmos are the manifest
Reality, He being the manifest. He is also their inner essence,
being also the unmanifest. He is the first, since He was when they
were not, and also the Last, since in their manifestation He is the
Essence. [BW X]
The eye perceives naught but Him. We are in His presence at all
times, in all states. [BW X]
God is essentially all things. He permeates through all beings
created and originated. [BW X]
He is Being itself, the Essence of Being, He is the Preserver of
all. In preserving all things, He is preserving His form, lest
anything should assume a form other than His Form, which is not
possible. [BW X]
The existence of all created things is His existence. Thou dost not
see, in this world or the next, anything beside God. [TB]
God is observer and observed.
He is the observer in the observer, and the observed in the
observed. [BW X] None sees Him, save Himself. None perceives Him,
save Himself. By Himself he sees Himself, and by Himself he knows
Himself. His Veil is part of his Oneness; nothing veils other than
he. . . His Prophet is he, and his sending is He, and His word is
He.[TB]
The knower and that which he knows are both one, and he who unites
and that with which he unites are one, and seer and seen are one.
[TB]
Identity of self and God.
Thou art not thou: thou art He. Thou never wast nor wilt be, Thou
art neither ceasing to be nor still existing. Thou art He.
[TB]
Thou art not what is beside God. Thou art thine own end and thine
own object in thy search after thy Lord. [TB]
He who knows himself understands that his existence is not his own
existence, but his existence is the existence of God.
[TB]
I also do not reject the teachings of Tao Te Ching. In fact, my
master, and the well-known Master Han Shan, praised Lao Tzu as a
Pratyekabuddha.
Even though they sound like Tao Te Ching, as far as I know, Lao Tzu
did not teach about God He only teach about the 'Unnameable Tao'. I believe
Jesus Christ is also enlightened. But the reason why he taught
about God is out of skillful means. Those people at that time
believe in God, so he present his most profound realisation,
ultimate truth of God to them. He definitely does not have the
common ordinary understanding of God as most others. You can read
the 'Gospel
of Thomas' about this. This is only my view, Dalai Lama's
views, mystics and other Buddhist's views. Christians probably
don't agree with me 
Jesus says: "If those who seek to
attract you say to you: 'See, the Kingdom is in heaven!' then the
birds of heaven will be there before you. If they say to you: 'It
is in the sea!' then the fish will be there before you. But
the kingdom is within you and it is outside of you!" 3 [3]. "When
you know yourselves, then you will be known, and you will know that
it is you who are the sons of the living Father. But if
you do not know yourselves, then you will be in a state of poverty,
and it is you the poverty!"
