All the religions in the world are the feathers of the same bird

[Caesar]

More relativism.

There is but a Single Truth, and that Truth is Christ and it is in His Holy Church.

You obviously have a gift for writing. If you or I were to start a religion today why would it be called “true” ? I don’t think it would. As for any religion, if one is a believer, one must ask what the God of the Religion asks of the members. If there are different answers, then maybe those religions are like the Romans and Greeks who had many gods.
Christianity according to my limited knowledge is the only one who has the God dying for His people, making a covenant with them and giving them the ability to live with Him forever if they grow in holiness.
I hope this helps your search for knowledge.

There is only one God and there is only one universe. Similarly the man is also only one.

This association has no premise; the oneness of God, the universe, and mankind are not correlated.

Man should aim that one God and he should belong to all the religions in the universe.

An impossibility when all religions preach a different God

He should pick up the diamonds from all the religions and use in his spiritual path.

Better yet, people should pick-up the diamonds God has revealed through his Church.

One can have love towards the nationality. Every nation has some physical boundaries. The people who are living in that nation have that nationality. Thus there is a meaning in the nationality because it has physical sense. But in the case of religion and spiritualism there is no physical sense.

Your assimilation here between nationality and faith is erroneous. Religion is confined to God’s revealed truth and in that way it does have boundaries.

Every religion belongs to every man. Therefore in religious and spiritual matters all the religions can be used.

Once again you have produced a false assimilation. Human’s quest to know God is written in our very being, as a result humanity will try different manners to do this but that does not mean all modes are either eventful or accurate in achieving communion with God. So no, not all religions can be used.

The human incarnation in every religion announces that He is the universal preacher.

Please provide evidence that this is so through history (say the last 2000 years) and a list of essential teachings they preached to see a consistent pattern.

The message of Lord Krishna i.e., Bhagavat Gita is for the entire world.

The message of Jesus i.e., Bible is for the entire world. The message of Mohammed is for the entire world. So there is no need of conversion of religions. Just like in science the invention of Einstein is useful for the whole world, every religious preaching is for everybody. Different scientists belonging to different countries have discovered different scientific inventions. The subject science contains all these inventions.
A person cannot possibly hold two mutually exclusive teachings as true. And being that many religions including Islam and Christianity are not homogeneous with each other your claim in all practicability is incorrect. And even to highlight the point with an example; which science is correct Copernicus’ or Galileo’s? If I base your answer with what you have already written you believe both to be correct…but you are incorrect.

Spiritualism means truth like science.

And like science there are propositions that are not true

The spiritualism requires divine virtues, which are emphasized in various religions. The firm faith of Islam, the infinite love of Christianity, the tolerance towards other religions of Hinduism, the social service of Bhuddhism and the non violence of Jainism are important virtues of the spiritualism. These are the practical traditional aspects of various religions, which are more precious than those scriptures. Tradition is the most important essence of the scripture.

Spiritualism first requires identifying God; second identifying our relation to him; thirdly identifying how to interact with him. Without first solving these questions spiritualism is meaningless as you have no certainty you are directing your spirituality to God. Interestingly the Spiritualism you wish to promote makes God irrelevant and you make the adhering to practising certain attributes the main precept for true spiritualism; this is incorrect. I.e. you make faith, love, and tolerance etc… the focus rather than God.
Also one must understand that knowing who God is cannot be completely deducted from reasoning we require God’s revelation to aid us. This revelation is what is present in Scripture and dogmas (or equivalent for other faiths). So spirituality is only fruitful if it is directed to the true God. The only way we can know if we believe in the true God is by understanding how he has revealed himself to us. The question then becomes which religion, if any, proclaims the true revelation of God. Being that all major religions differ in this key point, not all can be correct.

By trying to impose a non-existent harmony between all religions you disregard precisely what those religions preach. So you claim you uphold all religions but ultimately you end up upholding none.
