Is the Church Necessary?
WHY IS THE CHURCH NECESSARY IF NON-CATHOLICS CAN STILL BE SAVED?
The Church is necessary in spite of admitting the possible salvation of those who are not visible members because: a) Christ told the members of His Church to make converts of all nations; b) the saving message of Jesus Christ is the Truth so it is the right of every person to be made aware of it especially if it is the highest Truth, the Truth that leads to Heaven; c) non-Catholics lack all the helps that are available for salvation; d) no-one knows if they are in a state pleasing to God before death, least of all one who is without the ordinary means of salvation, namely, the Sacraments that Christ instituted through His Catholic Church.
YOU CATHOLICS HAVE GOT A SUPERIORITY COMPLEX!
Since the Church knows of no other means than Baptism by which a person can ordinarily be saved (Mk 16: 16 & Jn 3: 5), and since the saving message of Jesus Christ is the Truth, all Catholics have the responsibility to share their faith with others (Mt 28: 19-20; CCC 1257). However, being members of the "one, true Church" and having possession of the "fullness of the means of salvation" should not give Catholics any notion of superiority towards their non-Catholic brothers and sisters. In fact, Catholics (being in possession of the fullness of the means of salvation) will be more harshly judged, since in knowing more, more will be expected of them (Jas 3: 1).
THEN WHO WOULD WANT TO BE A CATHOLIC?!
With the greater dignity (becoming adopted sons and daughters of God through Baptism) so comes the greater responsibility, so comes all the grace necessary, since we have it on God's own word that He will never give any of us a cross too heavy to carry (1 Cor 10: 13).
