the question is not so different
Yes, they are. One deals with what a person must do to be saved, and another deals with the theoretical possibility that someone outside of the Church may be saved. The first we can know, the second we cannot. We do not have official proclamations about the efficacy of anything outside of our Church, whether we're talking about heterodox or non-Christians.
do you believe you must believe in Christ to be saved for starters, is that one of the things it takes to be saved ?
My personal belief? Yes, of course. Christ is the Savior of the whole world. There is no other name by which we may be saved.
if you say yes then how can non believers be saved?
I do not know. I don't mean that as a cop out, but I recognize that I do not understand God's ways, which are not my ways. I think it is probably most fair to say that anyone who gets into heaven, no matter who they are, is there despite themselves. For if you O Lord should mark iniquities, O Lord, who shall stand?
God has already revealed His judgement to us
In 140 A.D., the early Church Father Hermas quotes Jesus in John 3:5, and writes:
“They had need to come up through the water, so that they might be made alive;
for they could not otherwise enter into the kingdom of God.”119
This statement is obviously a paraphrase of John 3:5, and thus it demonstrates that
from the very beginning of the apostolic age it was held and taught by the fathers that
no one enters heaven without being born again of water and the Spirit based specifically on
Our Lord Jesus Christ’s declaration in John 3:5.
In 155 A.D., St. Justin the Martyr writes:
“... they are led by us to a place where there is water; and there they are reborn
in the same kind of rebirth in which we ourselves were reborn... in the name of
God... they receive the washing of water. For Christ said, ‘Unless you be reborn,
you shall not enter into the kingdom of heaven.’ The reason for doing this we
have learned from the apostles.”120
