There's your problem right there...We have the written words of God but yet your religion follows a man (group of men) who claim they and they alone have an inside track to the truth and revelation from God...
And this immaculate conception idea doesn't even come from the early tradition of your religion...It's a later invention...
You are following men in a man made religion and claim it's from God...It's the church Jesus founded...
Your religion defies scripture...
1Co 1:12 Now this I say, that every one of you saith, I am of Paul; and I of Apollos; and I of Cephas; and I of Christ.
1Co 1:13 Is Christ divided? was Paul crucified for you? or were ye baptized in the name of Paul?
1Co 3:22 Whether Paul, or Apollos, or Cephas, or the world, or life, or death, or things present, or things to come; all are yours;
1Co 3:23 And ye are Christ's; and Christ is God's.
The followers of the supposed sucsessors of Peter are nothing... We, who are in Christ are Christ's...
How do you know that's what they are? Who told you?
Open them up. You see that they say that the church is founded upon the apostles and prophets (Eph 2:20), and is the pillar and ground of the truth (1 Tm 3:15).
How can this be? Aren't the apostles and prophets mere men?
Our religion follows a man, all right. "The man Christ Jesus".
Is that some way of yours to try to say Catholics are "nothing?"
I mean, it wouldn't surprise me, given your posting history.
