The Westminster Confession of Faith boldly states of covenant baptism: "it is a great sin to contemn [to treat or regard with contempt] or neglect this ordinance." The Belgic Confesion Article 34 states:
...we detest the error of the Anabaptists, who are not content with the one only baptism they have once received, and moreover condemn the baptism of the infants of believers, whom we believe ought to be baptized and sealed with the sign of the covenant, as the children in Israel formerly were circumcised, upon the same promises which are made unto our children. And indeed Christ shed his blood no less for the washing of the children of the faithful, than for adult persons; and therefore they ought to receive the sign and sacrament of that, which Christ has done for them...
While many in Reformed churches still hold and practice these views, it is not uncommon to hear conservative Presbyterians state "baptism is a secondary issue, and it shouldn't divide us."
Since study committees are all the rage these days, I thought we should be reminded of a long-forgotten, dusty, neglected, old, study committee report: the 1966 OPC committee studying whether churches ought to receive into membership those who refuse baptism to their children. Their firm answer, "No."
The committee considers, however, that to admit to communicant membership those who "refuse" to present their children for baptism would constitute a weakening of the witness the church bears to the ordinance of infant baptism as one of divine warrant, authority, and obligation. Of greater weight is the fact that infant baptism is the way in which God continues to remind and assure us of that which belongs to the administration of his redemptive, covenantal purpose. The defect of the person not persuaded of this aspect of God's revealed counsel is not concerned with what is peripheral but with what is basic in the Christian institution. And the person who resolutely refuses to present his or her children for baptism is rejecting the covenant promise and grace which God has certified to his people from Abraham's day till now. It is this perspective that lends gravity to the offense. It is this estimate of baptism that underlies the statement of our subordinate standards when the Confession says that it is "a great sin to contemn or neglect this ordinance" (XXVIII, v) and the Directory for Worship that the children of the faithful "are holy in Christ, and as members of his church ought to be baptized" (IV, B, 4). It cannot be denied that the person refusing baptism for his children is delinquent in doctrine. It is the obligation of the session (in the case envisioned in this study) to apprise him of this. It is scarcely compatible with honesty, therefore, for such a person to answer in the affirmative such a question or any other form of question of similar purport as must be asked of those being received into communicant membership, namely, "Do you agree to submit in the Lord to the government of this church and, in case you should be found delinquent in doctrine or life, to heed its discipline?" (ibid., V, 5, 4).
In support and confirmation of the foregoing position the following additional considerations are offered.
1. God has revealed his great displeasure with those who refuse or neglect the administration of the sign of the covenant (Gen. 17:14; Exod. 4:24-26).
2. To refuse the covenant sign to the children of believers is to deny God's covenant claim upon them, and thus to withhold from him those who are rightfully his. Such denial provokes him to anger (Exod. 4:22-26; Mark 10:13, 14).
3. The riches of God's grace are most clearly seen in his covenant mercies, and to deny baptism to the children of the church prevents the grace of God from being seen in all its richness and manifestly detracts from its fullness. This cannot help but weaken the sense of gratitude in both parents and children and consequently rob God of the praise and thanksgiving that are due to him.
4. Those professing parents who refuse to present their children for baptism thereby deny their solemn obligation to keep God's covenant by raising their children in the knowledge and fear of the Lord, and deprive their children as well as themselves of the comfort
of God's covenant promise.
5. Professing parents who refuse to present their children for baptism withhold from the church of Christ the holy seed which God in his goodness has provided for it, and consequently deprive their children of the nurture and discipline which the body of Christ imparts to its members."

While the General Assembly voted to recommend that the matter of receiving members be left to the discretion of sessions, it sent this report to each session for study.
Maybe it should be republished?
