Are Lenten abstinences a rejection of the completed substitutionary atonement of Christ?
Former Roman Catholic T.A. McMahon writes:
I trusted in relics of dead so-called Saints; holy water; making the sign of the cross; votive candles; baptism for salvation (infant or otherwise); a “transubstantiated” piece of bread alleged to be Christ; apparitions of Mary; a scapular; a “miraculous medal”; statues and images of Jesus, Mary, and the saints; endless Rosaries, Novenas, the Stations of the Cross; abstaining from meat on Friday; Lenten abstinences; the Last Rites to get me into Purgatory and indulgences to get me out of Purgatory; Mass cards; graces dispensed from Mary; the confessional, with absolution of my sins by a priest; penance and personal suffering to purify me of my sin; worshiping a piece of bread at the Eucharistic Holy Hour; the Holy Father as the Vicar of Christ on earth, etc., etc. Therein lies a bondage that few evangelicals understand.
Many brush these things aside as non-essentials of the Christian faith or minor theological aberrations unique to Catholicism. Not true. They are essential to the gospel that Rome declares-a gospel of meritorious works that the Bible condemns (see Galatians, Romans, Ephesians, et al.) as a rejection of the completed substitutionary atonement of Christ our Savior. Catholicism’s Tradition, which is declared to be equal in authority to Scripture, is made up of those things (such as cited above) that are necessary for, or supportive of, a Catholic’s entrance into heaven.
According to the Word of God, anything that is added to Christ’s finished work on the cross is a denial of the gospel: that Christ paid the full penalty for the sins of humanity.
