Athee, the Catholic Church is a Hospital / Refuge for sinners, from the Pope on down to me. To say we who are members in the Catholic Church are not sinners, is making our Lord to be a liar.
Disagreement there is, The biggest would be Judas the betrayer one of the Lord Apostles who betrayed Jesus Christ with a Kiss. St. Peter, denied Our Lord three times, after our Lords resurrection St. Peter and St. Paul argued with one another, and on down to Priest molestation of Children, etc... etc... etc...
Jesus Christ left His Church founded on Rock, in the care of sinners, and what do sinners do? Sin! Jesus Christ was aware of this, thus why Jesus Christ left a Promise: Mathew 16: below:
Matthew 16: 18And I say to thee: That thou art Peter; and upon this rock I will build my church, and the gates of hell shall not prevail against it.
Athee, Note ..."Hell shall not prevail against it." Jesus did not say that hell will not try, but that it shall not prevail against it. Amen What Hell shall not prevail is the Catholic Church teachings inspired by the Holy Spirit for over 2000 years and counting.
Athee, you are blessed to have a wife who is a Christian, this is not a coincidence, but a God-incidence.
