Medical doctor and Islamic apologist Zakir Naik asserts the following:
1. The Quran and Bible say don’t eat pork, Muslims don’t, Christians do.
What is applicable to Jews is not always applicable to Christians, pork was an Old Testament Jewish (Hebrew) prohibition and is not applicable to Christians who are under the New Testament (and most are not ethnic Hebrews anyway).
2. The Quran and Bible say don’t have alcohol, Muslims don’t, Christians do.
There is no prohibition against alcohol (wine) in both the Old and New Testaments. There is a prohibition againt getting drunk, situational wine drinking which may lead to someone else becoming drunk and selective prohibition for one individual (John the Baptist).
3. The Quran and Bible say be circumcised, Muslims are, Christians are not.
What is applicable to Jews is not always applicable to Christians. Circumcision was the physical aspect of a covenant for the descendants of Abraham (i.e. Hebrews and Arabs [Egyptian/Hebrew]). Thus Naik as an Indian (Aryan/Dravidian) has no need to be circumcised and needs to re-attach his foreskin forthwith.
He also thinks that the Trinity refers to Jesus and the Father being one person. The Trinity relates to three persons of one divine essence.
NOTE: Naik can quote biblical and quranic scriptures fluently but that does not means he is a scholar or even correct. Naik has also refused to publicly debate Christians which is not the mark of someone who desires dialogue and truth.
