Don't cheat your family.  Religion is not as important as family .  If  you are going to hurt parents then why would you want to do it.

Seems like somebody must have braiwashed you. I have been to many churches. I went to catholic church they say they are too christian . I went to pentacost church they said they are true christian and others are fake. I went to mormon they said they are only true christian others are fake. Christians are confused amongst themselves.

You might say you are impressed with catholic friends life style. but reality is  e somebody is really pressurizing you to baptize. The truth is you want to get baptized because you have pressure from church people and nothing else. They are really good at it.

  or else why  you couldn't go to church without getting baptize.

Just go and tell them , your parents and family would never accept that and you will stick to your own religion.

You want' to hurt your family go ahead.
