re: I see nothing in God's word that marriage nor birth control is evidence of one being a Christian or not. Rather a real Christian will evidence the fruit of His Spirit
The evidence of the Holy Spirit IS THAT THEY REMAIN MARRIED FOR LIFE AND HAVE ALL THE CHILDREN GOD SENDS THEM (not use birth control). If you think other wise, that you can divorce and use birth control, you are just fooling yourself, you are no Christian. There are FEW in this world.
There is much more involved in becoming a son of God than just receiving Christ. Remember that the 5 foolish virgins low on oil (Mat 25:1-13), the man who buried the one talent (Mat 25:14-30), the man without the wedding garment (Mat 22:2-14), and the many, that will say Lord, Lord (Mat 7:22), all made an effort, and still were all thrown to hell.
And if the just man shall scarcely be saved, where shall the ungodly and the sinner appear? (1Peter 4:18)
Salvation is not a simple matter. Christ said that few will find it (Mat 7:14)
By their deeds you shall know them, if they are married for life and have not used contraceptives, they Christians, if not, they are false Christians on the road to perdition.
I will say again that God clearly states Salvation is in Christ alone and His finished work on our behalf....and certainly not in the doctrines of any specific church. Rather we become members of His body...His church...with Christ as head over all believers in every branch of Christian community...and the Vatican states that Christians are among those churches other than the Catholic Church alone as well. So adhereing to Catholic doctrine is not a requirement for Salvation...nor being a member of any specific church group....nothing in scripture supports your statement.
I do not support abortion and would find it very difficult to believe a Christian could carry this act through without ship-wreaking their faith. But there are many catholics who believe their reasons for allowing abortion does not exclude them from being a Christian regardless of catholic doctrine.
The evidence of being a Christian comes as the individual grows in the Grace and Knowledge of Christ....just as children make foolish decisions so too young Christians do as well...and they learn as they go until maturity in Christ. It is a lifetime of growth and allowing more and more of our life to reflect Christ as we yield those areas He chooses to change... to conform us to His image. But generally when one becomes a Christan there is evidence of changes in their life...but not always visible.
I see you likely adhere to what Rome teaches you should adhere to but there are many catholics who do not adhere to Rome. That is just reality.
