Actually it was the Church's ideas that brought women from second class status (at best) in the ancient world to the position of equality they enjoy today.
Women in the early church had considerably higher status--they were leaders of congregations and corresponded with as respect leaders by Paul--than have women in the Catholic church.
Where I think you (and many religious conservatives) and I (and many social liberals) disagree is the role of a higher authority in dictating choices--and which choices that higher authority should have the power to try to make on behalf of everyone in society.
If you believe God is in control and that He has (or should have) the ultimate power in deciding if sex should result in a pregnancy, then you oppose contraception as subverting the higher authority you believe everyone should be subject to, whether or not they share your religious beliefs.
If you don't believe in God or are religious but believe that God gives people the freedom to decide for themselves when to have sex, what partners to choose (maybe even a member of the same sex) and when and whether to have children, then you reject the idea of a church or the government or both dictating and trying to severely limit intensely personal choices regarding sex and reproduction with the force of law.
In America, we straddle that fence in favor of religious authority. Judges who make (what I consider) common sense rulings that a man who has fathered 14 or 15 kids and supports none of them financially must have a vasectomy are condemned and their rulings overturned, because they interfere with reproductive freedom. But women who seek early-term abortions--which most do for financial reasons-are also condemned even though the procedure is legal. We aren't consistent, partly because female contraception and abortion have been the primary targets of the policy war.
In a society in which separation of church and state is a basic tenet, the religious should not seek to limit every member of society's eproductive choices based on their view that God alone should have the authority to determine who is born.
