摘要
本文是由一行禪師之《生生基督世世佛》所引起的。該書强調耶穌基督與佛陀之間之共同點，並由此而結論只要信仰篤實、行其所信、信其所行，信耶穌或信佛陀，基本上沒有太大的差別。但由於作者本身是一位忠實之佛教禪師，因此在比較基督及佛陀時，始終以佛陀為主，基督副之：凡佛陀所在者，均設法在基督身上去找，凡佛陀所無者，则盡力或否認或認為「有所不妥」。因此，基督死後像復活以及聖父之子等教義，天主教視作信仰之基礎，作者竟不予認同。本文一方面指出，在信仰之實踐上，基督與佛陀確有十分相似之處，但在基本教理上，兩者尚有無可否認之差異存在。由《生生基督世世佛》引進另一位强調天主教與基督教十分相似之作者保羅蒂利希，作者由信仰之「終極關懷」論，進而推論出「既是終極關懷必須全力投入」，給前面所提之實踐信仰奠定了無可否認之基礎。唯此兩大宗教之相似處似乎到此為止，其基本教理之差異還很大。最後，本文以最簡單的提綱，提出天主教信仰之四大特徵：一、以基督為中心之信仰；二、以末世為目標之信仰；三、以神恩為助佑之信仰；以及四、以救贖為使命之信仰。

This article is a reflection on Zen Master Yi-Xing's book ”Living Buddha, Living Christ”. The book emphasizes the similarities between Christ and Buddha. From these similarities it is concluded that a sincere faith is important. As long as you do what you believe and believe what you do, there isn't a great difference between in whether you believe in Christ or Buddha. However, due to the fact that the author is a pious Zen master, when he compares Christ with Buddha, he tends to lean toward The Buddha, subjugating Christ to a secondary level. All characteristics that the Buddha possesses, he finds in Christ. Anything Christ possesses that the Buddha doesn't, he ignores or considers inappropriate. Therefore, the author doesn't concern himself with Christianity's basic notions of the resurrection and the trinity. This article on one hand contends that in implementing faith, Christianity and Buddhism have some similarities, however, their basic teachings have some marked differences that cannot be denied. From ”Living Buddha, Living Christ”, I will consider another author, Paul Tillich, who emphasizes the similarities between Catholicism and Protestantism. Tillich advances from faith’s ”ultimate concern” to the notion of ”total commitment”, giving practical faith an undeniable cornerstone. Even though Protestantism and Catholicism have similarities, they also have some glaring differences. Finally, this article would like to summarize four major points of the Catholic faith: 1.Jesus Christ as the focal point of faith. 2.Faith in the Eschatology. 3.Faith in the benevolent providence of God. 4.Faith in ultimate salvation.
