I'm a Roman Catholic and against freemasons.
Prayer for the Conversion of Masons
O Lord Jesus Christ. Who showest forth Thy omnipotence most manifestly when Thou sparest and hast compassion,
Thou Who didst say, “Pray for those who persecute and calumniate you, “ we implore the clemency of Thy Sacred Heart on behalf of souls, made in the image of God, but most miserably deceived by the treacherous snares of Freemasons, and going more and more astray in the way of perdition.
Let not the Church, Thy Spouse, any longer be oppressed by them; but, appeased by the intercession of the Blessed Virgin, Thy Mother, and the prayers of the just, be mindful of Thy infinite mercy, and disregarding their perversity, cause these very men to return to Thee, that they may bring consolation to the Church by a most abundant penance, make reparation for their misdeeds, and secure for themselves a glorious eternity;
Who livest and reignest world without end. Amen.
