No, Ephesians 2:8-9 says "for it is by grace you have been saved, not by works, but through faith, lest no one can boast".
To be a Christian, you must accept Jesus as your Savior.
John 14:6 Jesus said, "I am the Way, the Truth, and the Life. No one can come to the Father (and heaven) except through Me."
An affusion is a pouring of liquid, such in a Christian baptism where water is poured on the head of the person being baptised.
No. Anyone can get baptised: baptism is simply a way of showing that you are a Christian.
No the person would have to be still living. If someone has died without being baptised a 'Prayer for the dead' can be said and offered up.
no recording of him being baptised
Yes, his family is Christian.
One thing you might be is a Christian.
It's not required.
If you believe Jesus is a god then you are a Christian, baptised or not. There are also religions that believe in Jesus but do not believe him to be god. There is no evidence in their literature to suggest they will or can be abandoned by Jesus. If you are not a Christian or any other religion that believes in Jesus then the question is moot, it does not matter if Jesus abandons you.
Being a Christian without practice means you do not participate in the rituals of your religion, whereas just being a Christian can mean you do participate.
Christian and Catholic are the same thing. If you get baptised as a Catholic you are a Christian Catholic
You are baptised as a Christian. Despite what many think, baptism (in the name of the Father, Son and Holy Spirit) is a Christian sacrament and not a denominational one. That is to say, if you are baptised then you are baptised a Christian and not a Catholic, Anglican, Methodist or even a Baptist.
